Which of the following is a biodegradable polymer?

A) \[{{[-HN-{{(C{{H}_{2}})}_{5}}CONH-C{{H}_{2}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-]}_{n}}\]

B) \[{{[-HN-{{(C{{H}_{2}})}_{5}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-]}_{n}}\]

C) \[{{[-HN-{{(C{{H}_{2}})}_{6}}NHCO-{{(C{{H}_{2}})}_{4}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-]}_{n}}\]

D)

Correct Answer: A

Solution :

[a] \[n{{H}_{2}}N-C{{H}_{2}}-COOH+n{{H}_{2}}N-\] \[{{(C{{H}_{2}})}_{5}}-COOH\xrightarrow{{}}\]
