Type: MCQ-numerical-Easy-Class 12
In an SN1 reaction involving tert-butyl bromide and hydroxide ion in a polar protic solvent, what is the expected rate expression for the reaction?
A
Rate = k [tert-butyl bromide]
B
Rate = k [tert-butyl bromide][OH-]
C
Rate = k [OH-]
D
Rate = k [tert-butyl bromide]^2
Correct Answer
Option A
Detailed Explanation
The SN1 reaction follows first-order kinetics, where the rate depends only on the concentration of the tert-butyl bromide, as described in the NCERT context.
