Compound with most acidic hydrogen:
General Organic Chemistry (GOC) · Class 11 · JEE Main Previous Year Question
Compound with most acidic hydrogen:
- a
Option A
- b✓
Option B
- c
Option C
- d
Option D
Option B
Step 1: Identifying Active Methylene Compounds Acidity depends on the stability of the conjugate base anion.
- (B): Propane-1,2,3-tricarboxylate derivative. The hydrogen is alpha to three ester groups. The combined and effects provide massive stabilization.
- (D): Malononitrile (two groups). Extremely acidic, but fewer groups than B.
- (C): Acetone (one carbonyl).
- (A): Terminal alkyne ( CH).
Step 2: Conclusion Option B has three carbonyl-stabilizing groups for a single proton site.
