Question

Consider the given reaction and identify INCORRECT statement(s).

• A. Reaction involves formation of carbocation.
• B. Reaction proceeds by formation of transition state.
• C. Reaction follows 2nd order kinetics.
• D. Reaction proceeds with retention as well as inversion of configuration.

Answer 1

Answer: (A), (D)

Reaction involves formation of carbocation.
Reaction proceeds with retention as well as inversion of configuration.

Given reaction proceeds via $S_{N}2$ mechanism since complete inversion in configuration is observed, and in $S_{N}2$ only transition state is formed.

$S{N}^2$ mechanism does not proceed with the formation of carbocation.

Also, the only inversion of configuration and not retention of the configuration is obtained in this reaction.
