Which one of the following sets forms the biodegradable polymer?
Which one of the following sets forms the biodegradable polymer?
Options
- A and \mathrm{CH}=\mathrm{CH}
- B\mathrm{H}_2 \mathrm{~N}-\mathrm{CH}_2-\mathrm{COOH}\mathrm{H}_2 \mathrm{~N}-
- C and
- D
Correct answer
B. \mathrm{H}_2 \mathrm{~N}-\mathrm{CH}_2-\mathrm{COOH}\mathrm{H}_2 \mathrm{~N}-
Step-by-step solution
Biodegradable polymers have tendency to break down and lose their initial integrity.
\begin{aligned} \mathrm{H}}_{2} \mathrm{ N}-\mathrm{CH}}_{2}-\mathrm{COOH}+\mathrm{HNH}\left(\mathrm{CH}}_{2}\right)_5 \mathrm{COOH}\\
& \Delta \downarrow-\mathrm{H}}_{2} \mathrm{O}\\
& {\left[\mathrm{HN}-\mathrm{CH}}_{2}- \mathrm{CO}-\mathrm{NH}-\left(\mathrm{CH}}_{2}\right)_5-\mathrm{CO}_ n\right.} \\
