MCQ
What is the rate-determining step in an SN1 mechanism?
Chemistry
A Nucleophilic attack on the carbocation
B Loss of the leaving group to form the carbocation
C Deprotonation
D Formation of the transition state
Explanation

The slowest step in SN1 is ionization: the departure of the leaving group to form a carbocation intermediate. This step has the highest activation energy.
