This hydrocarbon is an aromatic hydrocarbon and also a cycloalkene. The Lewis structure is shown in the picture below.
Work Step by Step
This hydrocarbon is an aromatic hydrocarbon because the carbon ring on the left has a structure which is a derivative of the benzene ring, represented by a six-membered ring with three double bonds. And it is also a cycloalkene because the ring on the right has two double bonds. The Lewis structure is drawn the way the formula is shown in the question, with just hydrogens attached.
