Question

Arrange the following carbocations in the order of increasing stability.

(a) Benzyl > 3^0 > 2^0 > 1^0

(b) Benzyl > 1^0 > 2^0 > 3^0

(c) 3^0 > 2^0 > 1^0 > Benzyl

(d) 1^0 > 2^0 > 3^0 > Benzyl

The question was posed to me during an online exam.

Answer 1

Correct option is (a) Benzyl > 3^0 > 2^0 > 1^0

To explain I would say: The correct stability order of carbocation is- Benzyl > 3^0 > 2^0 > 1^0. Benzyl carbocation is the most stable and 1^0 carbocation is least stable.
