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.
