Question

Statement 1: Stability of carbanion follows the order shown. 
Statement 2: Allylic and benzylic carbanion stability is based on inductive effect and not resonance effect.

• A. Both Statement I and Statement II are correct
• B. Statement I is correct but Statement II is incorrect
• C. Statement I is incorrect but Statement II is correct
• D. Both Statement I and Statement II are incorrect

Answer 1

The Correct Option is B

Concept:
Carbanions are negatively charged carbon species. Their stability depends on several factors such as electronegativity of substituents, inductive effects, hybridization, and resonance. Step 1: Evaluate Statement 1. Carbanion stability increases when the negative charge is stabilized by electron-withdrawing groups or resonance. Thus the given stability order is correct. Step 2: Evaluate Statement 2. Allylic and benzylic carbanions are stabilized mainly by resonance. \[ \text{Allylic carbanion} \leftrightarrow \text{Resonance structures} \] \[ \text{Benzylic carbanion} \leftrightarrow \text{Resonance with aromatic ring} \] Hence stabilization is due to resonance, not inductive effect. Therefore Statement 2 is incorrect. Step 3: Final conclusion. \[ \boxed{\text{Statement I is correct but Statement II is incorrect}} \]
