Total number of resonating structures is :
Options:
Answer:
C
Solution:
The + charge sits at the exocyclic CH (next to the C=C). Moving the pi electrons gives + on the ring carbon that carries the exocyclic double bond, then on the ring carbon at the next position along the diene, then on the third carbon of the chain.
The + charge is delocalized over 4 carbon atoms, so there are 4 resonating structures.
