Least reactive alkyl chloride in a \(\mathrm{S}_{\mathrm{N}} 2\) reaction is
- A 1-Chloro butane
- B 1-Chloro 2-Methyl propane
- C 2-Chloro 2-Methyl propane
- D 2-Chloro butane
Answer & Solution
Correct Answer
(C) 2-Chloro 2-Methyl propane
Step-by-step Solution
Detailed explanation
An \(\mathrm{S}_{\mathrm{N}} 2\) reaction involves a single-step concerted mechanism and the alkyl halide that is most substituted at the \(\alpha\)-position will be least reactive. Thus, 2-chloro-2-methyl propane will be least reactive.
