SN1 Reaction - ANSWER- Unimolecular nucleophilic substitution - 2 steps - Starting with enantiomerically pure product tends to result in some degree of racemization - Retention AND inversion at stereocenter (R and S) - 1 nucleophile is replaced by another nucleophile - Carbocation INTERMEDIATE forms - Rate is dependent only on substrate concentration 1. LG leaves, forming a carbocation 2. Nucleophile attacks the carbocation, forming the product SN2 Reaction - ANSWER- Bimolecular nuc...
