Question

For \( P \), the incorrect statement is:

• A. \( P \) is less reactive than benzyl chloride towards nucleophilic substitution reaction.
• B. In \( P \), C-Cl bond has partial double bond character.
• C. \( Cl \) is an ortho-para directing group towards electrophilic aromatic substitution.
• D. \( P \) can undergo nucleophilic substitution reaction in normal conditions.

Hint:

In nucleophilic substitution reactions, benzyl and allyl halides are more reactive than other alkyl halides due to the stability of the transition state.

Answer 1

The Correct Option is D

Step 1: Analyze the reactivity.
- Statement (1) is correct, as benzyl chloride is more reactive than other alkyl chlorides towards nucleophilic substitution. - Statement (2) is correct. The C-Cl bond in \( P \) has partial double bond character due to resonance. - Statement (3) is correct. Chlorine is an ortho-para directing group in electrophilic aromatic substitution reactions. - Statement (4) is incorrect. \( P \) (which likely refers to a compound like \( \text{C}_6\text{H}_5\text{Cl} \)) does not easily undergo nucleophilic substitution under normal conditions. It requires special conditions, such as the presence of a strong nucleophile or elevated temperatures. Step 2: Conclusion.
Thus, the incorrect statement is (4). Final Answer: \[ \boxed{P \text{ can undergo nucleophilic substitution reaction in normal conditions}} \]
