Correct order of stability of above carbocations is:
General Organic Chemistry (GOC) · Class 11 · JEE Main Previous Year Question
Correct order of stability of above carbocations is:
- a✓
A > C > B > D
- b
D > B > C > A
- c
C > A > D > B
- d
D > B > A > C
A > C > B > D
Step 1: Evaluating Carbocation Stability
- (A) Benzyl Cation: High resonance stabilization from the phenyl ring. (Most stable).
- (C) Ethyl Cation: Stabilized by hyperconjugation ( and 3 H-atoms). (More stable than vinyl).
- (B) Vinyl Cation: Positive charge on carbon. (Very unstable).
- (D) Ethynyl Cation: Positive charge on carbon. (Least stable due to high electronegativity of carbon).
Step 2: Conclusion Order: (A) > (C) > (B) > (D).
Here is the complete list of carbocation stability based on real data from reputed organic book.
