Answer 2

Answer: vinyl chloride $CH_2=CHCl$

Explanation: PVC (Polyvinyl chloride) is formed by the polymerization of vinyl chloride monomers in a repeating manner. It is used in making of pipes, buckets etc.

Addition polymerization : A chemical reaction in which small units called as monomers are joined to form a bigger molecule called as polymer.  Example: PVC

Condensation polymerization : A chemical reaction in which small units called as monomers are joined to form a bigger molecule called as polymer and small by products are also formed along with the polymer. Example: Nylon 6,6

$nCH_2=CHCl\rightarrow (CH_2CHCl)_n$
