Note: Answer the question on the basis of information given below:
“Stability of carbocations depends upon the electron releasing inductive effect of groups adjacent to positively charged carbon atom involvement of neighbouring groups in hyperconjugation 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 given compound:
A resonance structure in which all atoms have complete octet will be more stable.
In resonance structure II, all atoms have complete octet while in structure I, carbon bearing positive charge is not having complete octet in their valence shell. Also, the stability increases with number of bonds formed. In structure II, there is one extra bond present than structure I.
So, structure II will be more stable.
