Given below are two statements :
Statement I: On the basis of the inductive effect, the order of stability of alkyl carbanions is CH₃⁻ > CH₃CH₂⁻ > (CH₃)₂CH⁻ > (CH₃)₃C⁻.
Statement II: Allyl and benzyl carbanions are more stabilized by the inductive effect and not by the resonance effect.
In the light of the above statements, choose the correct answer from the options given below.
Options:
Answer:
C
Solution:
Statement I is correct. Alkyl groups are electron-donating by inductive effect, destabilizing carbanions. Thus, CH₃⁻ (no alkyl groups) is most stable, and (CH₃)₃C⁻ (three alkyl groups) is least stable.
Statement II is incorrect. Allyl and benzyl carbanions are primarily stabilized by resonance, which delocalizes the negative charge, not by the inductive effect.
