Question

Given below are two statements labelled as Assertion (A) and Reason (R). Assertion (A): Benzyl carbocation is more stable than ethyl carbocation. Reason (R): Benzyl carbocation is resonance stabilized.

• A. Both A and R are true and R Is the correct explanation of A
• B. Both A and R are true but R Is not the correct explanation of A
• C. A Is true but R Is false
• D. A Is false but R Is true

Answer 1

Answer: (A)

Both A and R are true and R Is the correct explanation of A

Answer 2

Ethyl carbocation is stabilized by hyperconjugation. Benzyl carbocation is stabilized by resonance, which is a more effective stabilization mechanism than hyperconjugation. Therefore, benzyl carbocation is more stable than ethyl carbocation, and resonance stabilization is the reason for this.
