Question

Assertion :Aryl halides undergo nucleophilic substitution with ease. Reason: The carbon-halogen bond in aryl halides has partial double bond character.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Assertion is incorrect but Reason is correct

Answer 1

The correct option is D Assertion is incorrect but Reason is correct

Aryl halides do not undergo nucleophilic substitution reaction under ordinary conditions. Thus, statement $1$ is incorrect.

In aryl halides, the carbon-halogen bond has a partial double bond character, so it becomes shorter and stronger and cannot be easily replaced by a nucleophile.

Statement $1$ is false but statement $2$ is true.
