NEET Chemistry SN1 & SN2 Reactions MCQ Question

Type: MCQ-fact-Medium-Class 12

In SN1 reactions, the rate of reaction depends on the concentration of which reactant?

A

Tertiary halide

B

Nucleophile

C

Secondary halide

D

Polar solvent

Correct Answer

Option A

Detailed Explanation

In SN1 reactions, the rate of reaction depends solely on the concentration of the substrate, which is the tertiary halide, as it follows first order kinetics. This is highlighted in the context that the reaction between tert-butyl bromide and hydroxide ion yields tert-butyl alcohol and follows the first order kinetics.
