“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.” Draw the possible resonance structures for and predict which of the structures is more stable. Give reason for your answer.

The possible resonance structures for are shown below:

As we know that according to the octet rule; the stability of the resonating structure having complete octet of all the atoms present it that structure is more, hence the structure C is more stable than that of the structure A because, in structure C, octet of all the atoms is complete, whereas in structure A, C-atom having positive charge is not having 8 electrons in its valence shell.
