Allyl chloride (CH₂=CH–CH₂–Cl) ionises to give the allyl cation, represented by the two resonance structures CH₂=CH–CH₂⁺ ↔ ⁺CH₂–CH=CH₂. Which statement about this cation is correct? (A) The two resonance structures interconvert rapidly, and the cation exists as one structure at a time (B) The two structures are of identical energy and contribute equally, so the actual cation is a single delocalised hybrid more stable than either individual contributing structure (C) Only the first structure is correct, because the positive charge must remain on the carbon nearest the original C–Cl bond (D) The cation is destabilised relative to a simple (non-allylic) primary carbocation because the positive charge is spread over two carbons Show answer and explanation ← Question 7 All Organic Chemistry – Some Basic Principles and Techniques questions Question 9 → More NEET Chemistry chapters © 2026 Lumi (Aikolumi Software Pvt Ltd).
