Question

Choose the correct statement regarding the formation of carbocations A and B given.

• A. Carbocation A is more stable and formed relatively at a faster rate.
• B. Carbocation B is more stable and formed relatively at a faster rate.
• C. Carbocation A is more stable and formed relatively at a slow rate.
• D. Carbocation B is more stable and formed relatively at a slow rate.

Answer 1

The correct option is B

Carbocation B is more stable and formed relatively at a faster rate.

Explanation for correct option:

B carbocation is more stable due to more hyperconjugation and it forms a relatively faster rate compared to A.

This is more stable due to secondary cation formation and formed with faster rate due to low activation energy.

Hence, Carbocation B is more stable and formed relatively at a faster rate.

Explanation for incorrect option:

A,C and D are incorrect options because the given statements don't justify the stability and rate of carbocation formed.

Hence, options A,C and D are incorrect.
