Solution:

Nylon-66 is obtained by condensation copolymerisation of adipic acid and hexamethylene, diamine. $ \underset{\text{Hexamethylenen}\,\,\text{diamine}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\text{Adipic}\,\text{acid}}{\mathop{n{{H}_{2}}N-{{(C{{H}_{2}})}_{3}}-N{{H}_{2}}+nHO-\overset{O}{\mathop{\overset{\mathbf{|}\,\,\mathbf{|}}{\mathop{C}}\,}}\,-{{(C{{H}_{2}})}_{4}}-\overset{O}{\mathop{\overset{\mathbf{|}\,\,\mathbf{|}}{\mathop{C}}\,}}\,-OH}}\, $ $ \xrightarrow[-{{H}_{2}}O]{\Delta }\underset{{}}{\mathop{-\left[ \underset{Nylon-66}{\mathop{NH{{(C{{H}_{2}})}_{6}}NHCO{{(C{{H}_{2}})}_{4}}CO}}\, \right]-}}\, $
