Chemistry YouTube has a distinct split that does not exist in most other STEM subjects. On one side: accessible, enthusiastic channels that make chemical concepts understandable and enjoyable for students who find chemistry daunting. On the other: channels run by professional chemists who document actual laboratory work — synthesis videos, reaction demos, and research-level explanations that assume significant background knowledge.
The best YouTube channels for chemistry serve different needs, and the mistake self-learners make is picking the wrong tier for their stage. A first-year chemistry student watching NileRed's synthesis videos will be lost in the procedural detail. An organic chemistry student who has only watched Tyler DeWitt will have correct intuitions but no computational fluency. Understanding the landscape prevents those mismatches.
This guide covers the major chemistry YouTube channels organized by sub-topic — general chemistry, organic chemistry, physical chemistry, biochemistry — with honest notes on what each channel is for, what it does well, and how to combine channels into a coherent study system.

Tyler DeWitt — The Best Starting Point for Chemistry
Tyler DeWitt is the most effective gateway into chemistry on YouTube. His channel is explicitly designed for students who find chemistry intimidating or confusing, and it works because DeWitt has a genuine pedagogical gift: he can explain chemical concepts accurately without making them feel abstract or threatening.
The channel's style is conversational, enthusiastic, and consistently example-grounded. DeWitt uses analogies that do real explanatory work rather than oversimplifying — his analogy for ionic versus covalent bonding (sharing versus transferring electrons as lending versus giving away your lunch) is the kind of explanation that builds an accurate mental model while being genuinely easy to remember.
Key topics covered:
- Stoichiometry and mole calculations (the area where most students first struggle)
- Chemical formulas, naming compounds, balancing equations
- Atomic theory and electron configuration
- Acids and bases (conceptual understanding before the mathematics)
- Nuclear chemistry
- Organic chemistry basics
Who it is for: high school students in first-year chemistry, college students taking general chemistry for the first time, and anyone who hit a wall in chemistry and needs a reset. DeWitt's explanations are clear enough that they help even students who have been through the material before and feel confused.
What it is not: a source for quantitative problem-solving technique. DeWitt builds understanding; you need Khan Academy or a textbook for the calculation practice.
The specific gap DeWitt fills: chemistry is unusual among STEM subjects in how much of student failure comes from not understanding what is actually happening at the conceptual level before being asked to calculate. Students who do not understand what a mole represents conceptually — why it exists, what it is measuring — cannot do stoichiometry reliably even if they memorize the formula. DeWitt fixes the conceptual gap that most chemistry courses create by starting with calculation.
Crash Course Chemistry — Survey Coverage Done Well
Crash Course Chemistry (hosted by Hank Green, produced by John Green and the Crash Course team) covers the full general chemistry curriculum at a high-school to early-college level. The format is 10-12 minute episodes with consistent high production quality — animated graphics, humor, and fast-paced delivery.
The series covers: atomic structure, the periodic table, ionic and covalent bonding, thermodynamics, electrochemistry, nuclear chemistry, and organic chemistry introduction. Each episode is designed to provide a complete overview of a topic rather than deep instruction.
Who it is for: students who need a broad survey of general chemistry before a course begins, or who want to review a topic quickly before an exam. Crash Course Chemistry is not sufficient for passing a university general chemistry exam on its own, but it is excellent for establishing the terrain — knowing what everything is before you learn how each piece works in detail.
Specific use case: watch the relevant Crash Course episode before each unit of your general chemistry course. You will arrive knowing the vocabulary, the rough shape of the topic, and the connections to adjacent topics. The lecture will make more sense and you will have better questions. This is the most efficient use of Crash Course content.
The Hank Green advantage: Crash Course Chemistry is hosted more enthusiastically and with better conceptual framing than most comparable survey content. Hank Green has genuine enthusiasm for chemistry and it comes through in the delivery.
NileRed — Organic Chemistry and Professional Synthesis
NileRed (Nigel Braun) is the highest-production-quality chemistry channel on YouTube and occupies a unique niche: professional organic chemistry synthesis, documented in extraordinary visual detail. Braun has a chemistry degree and his videos document multi-hour synthesis procedures — extracting dye from plants, synthesizing pharmaceutical compounds, turning plastic bags into diesel fuel — with laboratory rigor and visual clarity that no other channel matches.
The channel's videos are not instructional in the conventional sense. NileRed does not teach you organic chemistry step by step — it shows professional organic chemistry being practiced, which is a different and equally valuable form of education. Watching NileRed builds intuition about how real laboratory chemistry works: the practical challenges, the error modes, the gap between textbook reactions and bench chemistry.
Who it is for:
- Organic chemistry students who want to see textbook reactions executed in a real laboratory
- Anyone who wants to understand what professional chemistry actually looks like
- Students considering chemistry careers who want a realistic picture of laboratory work
Prerequisites: NileRed assumes familiarity with basic organic chemistry concepts — functional groups, reaction types, laboratory technique. Watching without this background produces appreciation for the visuals without understanding the chemistry.
The most-watched videos:
- "I Made Neon from Scratch"
- "Turning old plastic bags into diesel fuel"
- "Making aerogel" (the lightest solid known)
- "Extracting caffeine from tea"
- "Synthesizing spider silk" (attempted — the failures are as educational as successes)
NileBlue (Braun's secondary channel) covers shorter chemistry content and commentary on chemistry videos from other creators, including corrections and context that the main channel format does not allow.
Khan Academy Chemistry — The Problem-Drilling Resource
Khan Academy's chemistry content is less visually exciting than the channels above but more systematically useful for students who need to build quantitative chemistry skills. The exercises on stoichiometry, electrochemistry, equilibrium constants, thermodynamics calculations, and acid-base chemistry are well-designed, include immediate feedback, and are organized into mastery progressions.
Where Khan Academy is irreplaceable:
- Stoichiometry calculation practice (limiting reagents, percent yield, empirical formulas)
- Acid-base chemistry calculations (pH, pOH, buffer calculations)
- Thermodynamics calculations (Hess's law, enthalpy, Gibbs free energy)
- Electrochemistry (cell potentials, Faraday's constant calculations)
- Equilibrium calculations (ICE tables, Ka/Kb expressions)
For these topics, the Khan Academy exercise bank combined with conceptual explanations from Tyler DeWitt or Crash Course gives you the full learning stack: understand what you are doing, then practice doing it until it is automatic.
The general chemistry progression on Khan Academy: the Unit 1-9 structure maps reasonably well onto a first-year university general chemistry course. Students who complete the units with mastery on exercises will have covered the material at a level that prepares them for introductory university coursework.
Professor Dave Explains — Comprehensive and Methodical
Professor Dave Explains (Dave Farina) has built one of the most comprehensive free chemistry curricula on YouTube. The channel covers general chemistry, organic chemistry, biochemistry, and physical chemistry in extended playlist series — each playlist effectively constituting a free course with clear learning progression.
Dave's style is whiteboard-based and methodical. He works through the material systematically, covering both conceptual explanation and quantitative technique. His organic chemistry series is particularly strong — covering mechanisms, stereochemistry, and multistep synthesis in a way that prepares students for second-year university organic chemistry.
Who it is for:
- Students who need a complete coverage resource — something that will walk them through an entire course, not just difficult topics
- Students studying organic chemistry who find the mechanisms section particularly difficult
- Self-learners building a chemistry education without a course structure
How it compares to Tyler DeWitt: DeWitt is better for initial conceptual understanding; Professor Dave is better for systematic course-level coverage. DeWitt will help you understand what a reaction is doing; Professor Dave will walk you through mechanisms and give you the procedural knowledge to apply the reaction in new contexts.
The organic chemistry playlist is the channel's most useful content for university students. The playlist covers all major reaction types (alkyl halide reactions, alcohols, aldehydes and ketones, carboxylic acid derivatives, amines) with both conceptual explanation and mechanism detail.
Is There a Good Physical Chemistry Channel?
Physical chemistry — quantum chemistry, thermodynamics, statistical mechanics, spectroscopy — is underserved on YouTube compared to general and organic chemistry. This reflects the subject's difficulty: it requires calculus, differential equations, and linear algebra, which raises the entry barrier for both creators and audiences.
The best currently available resources:
MIT OpenCourseWare 5.61 (Physical Chemistry) has lecture recordings available. The course covers quantum mechanics applied to atoms and molecules, molecular spectroscopy, and statistical mechanics. The MIT OCW version includes problem sets and exams, making it usable as a complete self-study course.
PBS Space Time, while primarily a physics channel, covers quantum mechanics at a level that is directly relevant to quantum chemistry. The series on quantum field theory and the structure of atoms complements physical chemistry coursework.
Atkins' Physical Chemistry official resources (many unofficial walkthrough videos on YouTube) cover the standard physical chemistry curriculum. Search for the specific topics (Born-Oppenheimer approximation, Hartree-Fock methods, partition functions) alongside "lecture" or "explained."

How to Structure a Self-Directed Chemistry Education Using YouTube
The three-tier structure that works for most self-learners:
Tier 1 — Conceptual understanding:
- Tyler DeWitt for general chemistry concepts
- Crash Course Chemistry for survey coverage
- NileRed for organic chemistry intuition through observation
Tier 2 — Systematic instruction:
- Professor Dave Explains for course-level coverage of general and organic chemistry
- Khan Academy for exercises and mastery assessment
- MIT OCW for physical chemistry at university rigor
Tier 3 — Deep and applied:
- NileRed for seeing chemistry practiced
- ACS (American Chemical Society) lectures and symposia for research-level content
- HHMI BioInteractive for biochemistry at the molecular biology interface
For foundational chemistry at the high school through early university level, the American Chemical Society maintains free chemistry education resources at acs.org, including learning guides aligned to major general chemistry textbooks.
The most common self-study mistake in chemistry: spending too much time watching without doing calculations. Chemistry is quantitative in ways that are invisible from videos. You can understand Le Chatelier's principle conceptually from a Crash Course video and still be unable to set up and solve an equilibrium calculation correctly. The calculation practice is non-optional. Use Khan Academy's exercise bank as the problem source, and treat your self-assessment honestly — if you cannot get the answer without looking at examples, you have not learned the technique.
What Makes Chemistry YouTube Different from Physics and Math YouTube?
Chemistry YouTube has a larger population of laboratory demonstration channels — channels whose primary value is watching reactions happen — than physics or math YouTube does. This is partly inherent to the subject: chemistry is visual in a way that mathematics is not, and reactions (explosions, color changes, phase transitions, crystallization) are intrinsically engaging to watch.
The pedagogical risk this creates: it is easy to spend many hours watching chemistry reactions on YouTube and come away with the feeling that you understand chemistry when you have actually built an appreciation for how dramatic chemical change can be. Those are not the same thing.
The channels that bridge this gap best: Tyler DeWitt (uses demonstration-style explanation but always explains the underlying chemistry), Professor Dave (systematic instruction that ties conceptual explanation to calculation), and Khan Academy (pure calculation practice with no entertainment component to distract from the skill-building).
The most honest framing for chemistry YouTube use: treat visual demonstration channels (NileRed, chemistry demonstration channels) as motivation and contextual enrichment. Treat Tyler DeWitt and Professor Dave as primary instruction. Treat Khan Academy as your assessment and practice system. The combination builds both genuine understanding and the computational skills that chemistry exams test.
Taking Notes on Chemistry YouTube Videos — What Works
Chemistry video notes require capturing different things depending on the type of content:
For conceptual videos (Tyler DeWitt, Crash Course): write down the core model — what is the structure, what does it explain, what are the edge cases the instructor mentions. For ionic vs. covalent bonding, your notes should answer: what determines which type of bonding occurs, what properties result from each type, and what examples were given.
For procedural/calculation videos (Khan Academy, Professor Dave): write down the steps as you understand them, then close the video and work a parallel problem from a textbook or Khan Academy exercises. If you cannot execute the procedure without looking at your notes, the procedure is not yet in your working knowledge.
For laboratory videos (NileRed): note the reaction being performed, the key procedural decisions the chemist makes, and any unexpected outcomes or troubleshooting. This builds laboratory intuition that textbooks cannot.
For a system that turns chemistry lecture notes into structured review materials automatically, the AI study notes guide covers the complete workflow. For the note-taking method itself, see take notes from YouTube lecture.
The best YouTube channels for chemistry give you access to instruction ranging from Tyler DeWitt's patient explanation of what a mole actually is to NileRed's professional synthesis work to MIT's physical chemistry curriculum. The quality of what is available for free is genuinely remarkable.
The discipline required to use it well is the same as in any subject: watch with intent, take notes that require recall rather than recognition, and work problems. The videos are the instruction; the problems are the learning.
