[2012 M]
(a) $CH_2=CH-CN$ and $CH_2=CH-CH=CH_2$
(b) $H_2 N-CH_2-COOH$ and
$ H_2 N-(CH_2)_5-COOH $
(c) $HO-CH_2-CH_2-OH$ and
(d)
$CH_2=CH-CH=CH_2$
Show Answer
Solution:
- (b) Biodegradable polymer is Nylon-2Nylon-6 which is copolymer of glycine $(H_2 N-CH_2-COOH)$ and amino caproic acid $(H_2 N-(CH_2)_5-COOH)$.
$ \begin{aligned} & nH_2 N-CH_2-COOH+ \\ & \text{ glycine } \quad nH_2 N-(CH_2)_5-COOH \end{aligned} $
$ \text{ nylon }-2-\text{ nylon }-6 $
