Chemistry-SN1 & SN2 Reactions
NEET Chemistry SN1 & SN2 Reactions MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Which of the following statements about SN1 and SN2 reactions is correct?
A
SN1 reactions occur in a single step and involve the formation of a carbocation.
B
SN2 reactions are characterized by a two-step mechanism and depend on the concentration of both reactants.
C
The rate of SN1 reactions depends on the concentration of only the alkyl halide involved.
D
SN2 reactions are favored by polar protic solvents due to their ability to stabilize carbocations.
Correct Answer
Option C
Detailed Explanation
SN1 reactions involve the formation of a carbocation and follow first-order kinetics, meaning the rate depends solely on the concentration of the alkyl halide. This matches the NCERT context, which details the mechanism and kinetics of SN1 reactions.
