NEET Chemistry (general) MCQ Question
Type: MCQ-numerical-Easy-Class 12
Which of the following compounds will react faster in an SN2 reaction with hydroxide ion (OH−)?
A
CH3Br
B
CH3I
C
(CH3)3CCl
D
CH3Cl
Correct Answer
Option B
Detailed Explanation
In SN2 reactions, the reactivity is influenced by the leaving group ability. Iodide (I−) is a better leaving group than bromide (Br−), so CH3I reacts faster than CH3Br. Similarly, sterically hindered tertiary halides like (CH3)3CCl react slower than primary halides.
