Nylon-6 6 is obtained from

A)  adipic acid and hexamethylene diamine

B)  tetrafluoroethylene

C)  vinyl cyanide

D)  vinyl benzene

Correct Answer: A

Solution :

                The monomer units of nylon-6 6 are hexamethylene diamine and adipic acid. \[\underset{~hexamethylene\text{ }diamine}{\mathop{n{{H}_{2}}N-{{(C{{H}_{2}})}_{6}}-N{{H}_{2}}}}\,\] \[+nHO-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-\underset{adipic\,acid}{\mathop{{{(C{{H}_{2}})}_{4}}}}\,-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-OH\]
