Question

Aryl halides are highly reactive towards nucleophilic substitution reactions. In case of haloarenes, halogen atom is attached to sp hybridised carbon atom.

• A. If both assertion and reason are true and reason is the correct explanation of assertion.
• B. If both assertion and reason are true but reason is not the correct explanation of assertion.
• C. If assertion is true but reason is false
• D. If both assertion and reason are false.

Answer 1

Answer: (D)

If both assertion and reason are false.

Answer 2

Aryl halides are less reactive towards nucleophilic substitution reactions as $C??$ bond aquires a partial double bond character due to resonance. Also halogen atom is attached to $sp^{2 }$ hybridised carbon atom.
