As we know that the, stability of carbocation can be decided by many effects, like inductive effect, resonance, hyperconjugation etc. And a combined effect leads to the following order of stability of carbocation:

As structure A is having a carbocation, which is primary and allylic carbocation, whereas the carbocation in the structure B has secondary and allylic carbocation.

Hence, structure B is more stable.

(NOTE: As in both cases the allylic carbocation is common, it will not be the deciding factor for stability, hence we will decide the stability by primary and secondary carbocation.

“Stability of carbocation depends upon the electron releasing inductive effect of groups adjacent to positively charged carbon atom involvement of neighbouring groups in hyper-conjugation and resonance.”Which of the following ions is more stable? Use resonance to explain your answer.
