Question

Which of the following factors has no effect on the rate of SN1 reactions?
Options
A the nature of the alkyl halide
B the nature of the leaving group
C the concentration of the alkyl halide
D the concentration of the nucleophile
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

The rate of an SN1 reaction depends only on the concentration of the alkyl halide (and factors affecting carbocation formation like the nature of the alkyl halide and leaving group). The concentration of the nucleophile does not affect the rate because the nucleophile is not involved in the rate-determining step.

Hint

What is not involved in the rate-determining step of SN1?
