Answer 1

Answer: (C)

(A) Natural rubber is cis-polyisoprene with formula.

(B) PVC is polyvinyl chloride with formula
$CH _{2}= CH \cdot Cl$. It will show free radical polymerisation.
(C) Terylene is also called dacron with formula.

It is formed by condensation polymerisation using.

(D) Syndiotactic polymer is molecule in which, we have substituents at alternate positions along the chain.
