Organic Chemistry Flashcards

This deck spans the full sequence most students take across two semesters of organic chemistry: structure and bonding (hybridization, resonance, formal charge), stereochemistry (chirality, R/S, E/Z, optical activity), functional groups and nomenclature, reaction mechanisms (SN1, SN2, E1, E2, addition, elimination), spectroscopy (IR, NMR, mass spec interpretation), and multi-step synthesis. Cards are built around the patterns that show up on ACS final exams and MCAT organic questions.

The free preview shows five sample cards. Inside the Sticky app you get the complete deck, generated from your textbook or lecture notes and scheduled with spaced repetition so the mechanisms you learned in week three return on the right day to keep them in long-term memory.

Organic chemistry is the class where the "memorize everything" strategy fails hardest. The exam asks you to predict products of reactions you have never seen, which only works if you understand mechanisms. Flashcards still earn their keep, but only if you build the right kinds of cards:

1. Lock in functional groups and reagent roles first. Before any mechanism makes sense, you need to know what each functional group looks like and what each common reagent does (oxidizer, reducer, nucleophile, base). These are pure recall and belong on flashcards.
2. Build reaction-condition cards, not product cards. A card asking "what conditions favor SN2 over SN1?" trains the pattern recognition the exam tests. A card asking "what is the product of this reaction?" can usually be derived from the conditions.
3. Draw mechanisms from memory. After reviewing a reaction card, take 60 seconds to push arrows on paper. This is the strongest form of active recall for organic chemistry.
4. Review daily, in 20-minute blocks. The spacing effect matters even more here than in other STEM courses because each new chapter assumes mastery of every previous mechanism.
5. Practice synthesis problems separately. Flashcards build the toolkit. Multi-step synthesis questions train the strategic thinking that ties the toolkit together.

Both ACS exam item statistics and MCAT content outlines emphasize the same core themes. Make sure your flashcard rotation overweights these:

• SN1, SN2, E1, E2 selectivity: substrate, nucleophile/base strength, solvent, temperature
• Markovnikov and anti-Markovnikov addition: HBr vs HBr/peroxides, hydroboration-oxidation
• Stereochemistry assignment: R/S priority rules, meso compounds, diastereomers vs enantiomers
• Carbonyl chemistry: aldol, Claisen, enolate alkylation, Grignard additions
• Aromatic substitution: directing effects of common substituents in EAS reactions
• NMR interpretation: chemical shift, multiplicity, integration, coupling constants

Most organic students lose hours re-reading their notes and highlighting reaction schemes. The problem is that recognition is not recall. You can read a mechanism, feel like you know it, and then blank on the exam. Active recall, the kind your brain does when you flip a card and force yourself to produce the answer, builds the retrieval pathway exam questions actually test.

Layered on top, spaced repetition stops you from forgetting earlier-chapter mechanisms while you cover new ones. By the time you reach the final, the SN2 mechanism from week two is just as fresh as the Diels-Alder you learned last week. That is the only way to walk into a cumulative exam without spending the prior weekend trying to relearn the entire semester.
