Question

Identify the monomer in the following polymeric structure.

A


B

Answer 1

$\text{A. Monomer for given polymer}$


This polymeric structure is formed upon condensation of decanoic acid and hexamethylenediamine.


Hence, the monomers of the given polymer are hexamethylene diamine and decanoic acid.

$\text{Final answer:}$

$\left(i\right)$ $\begin{array}{cc}{H}_{2}N(C{H}_2{)}_{6}N{H}_2& \\ Hexamethylenediamine& \end{array}$


$\left(ii\right)$ $\begin{array}{cc}HOOC(C{H}_2{)}_{8}COOH& \\ Decanoicacid& \end{array}$


$\text{B. Monomer for given polymer}$


The given polymer is a melamine polymer. It is formed by condensation polymerization of Melamine and formaldehyde $\left(HCHO\right)$.

Polymerisation reaction of given polymer is shown as -


Hence, the monomers of the given polymer are Melamine and formaldehyde $\left(HCHO\right)$.

$\text{Final answer:}$

$\left(i\right)$ Melamine

$\left(ii\right)$ Formaldehyde
