Question

Which of the following compounds would react most rapidly in an SN2 reaction?
Options
A CH3CH2I
Correct Answer
B CH2=CH–I
C (CH3)2CHI
D (CH3)3CI
Correct Answer

Option A is the correct answer.

Detailed Explanation

SN2 reactions are fastest with primary alkyl halides (least steric hindrance). CH3CH2I is a primary alkyl iodide and will react most rapidly. CH2=CH-I is vinylic (unreactive), (CH3)2CHI is secondary, and (CH3)3CI is tertiary.

Hint

Which alkyl halide is least hindered and primary?
