Aryl Halides are less reactive towards nucleophilic substitution reactions because of:
(A) Resonance Effect
(B) Stability of phenyl cation
(C) Presence of sp² Carbon attached to halogen
(D) Repulsion between benzene ring and incoming nucleophile
Choose the correct answer from the options given below:
- A (A), (C) and (D) only
- B (A), (B) and (C) only
- C (A), (B), (C) and (D)
- D (B), (C) and (D) only
Answer & Solution
Correct Answer
(A) (A), (C) and (D) only
Step-by-step Solution
Detailed explanation
Aryl halides are less reactive toward nucleophilic substitution due to: (A) Resonance effect The lone pair on halogen participates in resonance with the benzene ring, giving the C–X bond partial double bond character, making it stronger and harder to break. (B) Stability of…
