There is a chlorine (Cl) atom on the seventh carbon atom; numbering from the carbonyl group and counting the carbonyl carbon atom as C1, we place the Cl atom on the seventh carbon atom. It is mainly used as a precursor to polymers. A carbon-carbon double bond and a hydroxyl group (there are eight).
