Question

Which is the most stable carbocation?​

Answer 1

Among the given options, the most stable carbocation is: (A) CH3CH⁺CH2I.

- The stability of the carbocations increases in the order: Primary < Secondary < Tertiary.

- Option (A) CH3CH⁺CH2I is a secondary carbocation.

- Option (B) CH2⁺CH2CH2I is a primary carbocation.

- Being a secondary carbocation, CH3CH⁺CH2I is more stable than the primary carbocation CH2⁺CH2CH2I.

- Hence, option (A) is more stable in comparison to option (B).

Answer 2

Answer:

         (+)

CH3-CH-CH2-I  is more stable as it is secondary carbocation with 4H.C. while (B) has only 2H.C.
