Each of these questions contains two statements: Statement 1 and Statement2. Each of these questions has four alternative choices, only one of which is the correct answer.
Statment 1 : `S_N2` reaction of an optically active aryl halide with an aqueous solution of KOH always gives an alcohol with opposite sign of rotation.
Statement 2: `S_N2` reactions always proceed with inversion of configuration

A

Statement 1 is True, Statement 2 is True, Statement 2 is Correct explanation for Statement 1.

B

Statement 1 is True, Statement 2 is True, Statement 2 is NOT a correct explanation for Statement 1.

C

Statement 1 is True, Statement 2 is False.

D

Statement 1 is False, Statement 2 is True.

Text Solution

Verified by Experts

The correct Answer is:
D
Statement 1 is false, because aryl halides do not undergo nucleophilic substitution under ordinary conditions. This is due to resonance, because of which the carbon-chlorine bond acquires partial double bond character, hence it becomes shorter and stronger and thus cannot be replaced by nucleophiles.
