NEET Chemistry SN1 & SN2 Reactions MCQ Question
Which of the following statements about SN1 and SN2 reactions is correct?
SN1 reactions occur in a single step and involve the formation of a carbocation.
SN2 reactions are characterized by a two-step mechanism and depend on the concentration of both reactants.
The rate of SN1 reactions depends on the concentration of only the alkyl halide involved.
SN2 reactions are favored by polar protic solvents due to their ability to stabilize carbocations.
Correct Answer
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.
