- A. Vinyl Chloride
- B. Vinyl acetate
- C. Formaldehyde
- D. Methyl methacrylate
Explanation
Polyvinyl acetate is formed by addition polymerisation of vinyl acetate, CH2=CH-OCOCH3, with the double bond opening to make the polymer chain. Vinyl chloride forms PVC, so students who associate the word “vinyl” only with a common vinyl polymer may choose option a.

About Polymers
Polymers are large molecules made from repeating monomer units joined by covalent bonds. The topic distinguishes addition polymers such as polyethylene, PVC and polystyrene from condensation polymers such as nylon and polyester, and relates chain structure to thermoplastics, thermosetting polymers, elastomers, properties, uses and environmental concerns.
