MCQ
In SN1 reactions, what is the stereochemical outcome when the starting material is a single enantiomer?
Chemistry
A Complete retention of configuration
B Complete inversion of configuration
C Racemization with some inversion
D Complete retention only
Explanation

SN1 proceeds through a planar carbocation intermediate. Nucleophilic attack from both faces gives racemization, but ion pairing often causes slight excess inversion.
