Organic Chemistry - Lecture 12
Key Reactions
SN1 reactions proceed through a carbocation intermediate
SN2 reactions occur in a single concerted step with backside attack
Leaving group ability: I > Br > Cl > F
Key Concept: Substrate structure determines the dominant mechanism -- primary substrates favor SN2, tertiary favor SN1.
Smart flashcards with spaced repetition
Automatically generated flashcards from your content. Built-in SM-2 spaced repetition ensures you review at the optimal time.
