Khan Academy — Organic Chemistry

Main page: khanacademy.org/science/organic-chemistry

Khan Academy provides structured video lessons covering most topics in Organic Chemistry I and II, as well as general chemistry review. The organic chemistry section is particularly strong on foundational topics including functional groups, resonance, acids and bases, and reaction mechanisms. Topics are organized into units with videos, articles, and practice exercises.

Best used for: Initial exposure to a topic, foundational concept review, and acid-base chemistry.

Organic Chemistry Tutor

YouTube channel: The Organic Chemistry Tutor

An extensive library of problem-focused videos covering nearly every topic in both semesters of organic chemistry. Particularly useful for worked examples and visual walkthroughs of mechanisms.

Best used for: Mechanism walkthroughs, SN1/SN2/E1/E2 comparisons, stereochemistry, and spectroscopy interpretation.

Organic Chemistry playlist: Organic Chemistry — Professor Dave Explains

Clear, conversational explanations of organic chemistry topics in short videos. Strong coverage of nomenclature, functional groups, and spectroscopy.

Best used for: Quick introductions, nomenclature, NMR and IR fundamentals.

Master Organic Chemistry

Main page: masterorganicchemistry.com

A well-organized website designed specifically for organic chemistry students. Offers concise articles on most major topics, an extensive pKa table, and focused explanations of common problem areas. The articles go deeper than most videos and are especially strong on reasoning through mechanisms rather than memorizing them.

Best used for: Targeted topic review, pKa reference, understanding acidity trends, and troubleshooting difficult concepts.

LibreTexts Organic Chemistry

Main page: Organic Chemistry (Morsch et al.) — LibreTexts

A comprehensive open-access organic chemistry textbook. Useful as a primary reading source when a more thorough explanation is needed than a video provides. Covers the full two-semester sequence.

Best used for: In-depth reading on any topic, as a supplement to or replacement for a commercial textbook.
