NEET Chemistry SN1 & SN2 Reactions MCQ Question

Type: MCQ-conceptual-Medium-Class 12

Given that t-butyl bromide reacts with hydroxide ion in a polar protic solvent, calculate the rate of reaction if the concentration of t-butyl bromide is doubled, assuming it follows first-order kinetics.

A

Rate remains the same.

B

Rate doubles.

C

Rate triples.

D

Rate quadruples.

Correct Answer

Option B

Detailed Explanation

In SN1 reactions, like the reaction of t-butyl bromide with hydroxide ion, the rate depends only on the concentration of the substrate. Doubling the concentration of t-butyl bromide doubles the rate of reaction.
