Q. Natural rubber is a polymer of
A) Styrene
B) Chloroprene
C) ${CH}_{2} = C - CH = {CH}_{2}$ or isoprene
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ |\ \$
$CH_{3}$
D) 1,3 butadiene
Explanation
(c)
The commercial natural rubber is obtained from the tree Heveabrasiliensis. Natural rubber is found to be a polymer of cis-isoprene.
$CH_{2} = CCH = CH_{2}$
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ |\ \$
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ CH_{3}$
Hence, it is a polymer of cis-isoprene.
