Neet Solved Paper 2015 Question 42

Question: Biodegradable polymer which can be produced from glycine and aminocapric acid is

Options:

A) nylon 2-nylon 6

B) PHBV

C) buna-N

D) nylon-6, 6

Show Answer

Answer:

Correct Answer: A

Solution:

Nylon-2-nylon-6 It is an alternating polyamide of glycine (containing two carbon atoms) and ammo caproic acid or 6-aminohexanoic acid (containing six carbon atoms).

$ \underset{Glycine}{\mathop{nH _2N}}\ -CH _2-COOH+ $ $ \underset{Aminocaproicacid}{\mathop{nH _2N-{{(CH _2)}_5}-COOH\xrightarrow{\ }}}\ $ $ \underset{\begin{smallmatrix} \\ \text{Nylon-2-nylon-6} \end{smallmatrix}}{\mathop{-[ NH-CH _2-\underset{\begin{smallmatrix} || \\ O \end{smallmatrix}}{\mathop{C}}\ -NH-{{(CH _2)}_5}-\underset{\begin{smallmatrix} || \\ O \end{smallmatrix}}{\mathop{C}}\ ]-}}\ $

It is a biodegradable step-growth copolymer.
