Question
Which of the following factors has no effect on the rate of SN1 reactions?
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?
