Answer

This hydrocarbon is a cycloalkane and an alkene. The Lewis structure is shown in the picture below.

Work Step by Step

This hydrocarbon is a cycloalkane because the ring contains only single bonds. Even though the $CH=CH_2$ side chain contains a double bond, it is still a cycloalkane and this alkene is separate from the ring. The Lewis structure is drawn the way the formula is written, with a double bond between the two carbons in the side chain.
