JEE Main 2026 Chemistry question

ChemistryOrganic Chemistry - Some Basic Principles and TechniquesJEE Main 2026

Given below are two statements: Statement I: On the basis of inductive effect, the order of stability of alkyl carbanions is CH₃⁻ > CH₃-CH₂⁻ > (CH₃)₂CH⁻ > (CH₃)₃C⁻. Statement II: Allyl and benzyl carbanions are more stabilised by inductive effect and not by resonance effect.

Answer: (C)

Solution

Statement I correctly reflects that more alkyl (+I, electron-donating) substitution destabilises a carbanion.
