    Which compound/set of compounds is used in the manufacture of nylon-66?   

    A)  \[HOOC{{(C{{H}_{2}})}_{4}}COOH+{{H}_{2}}N{{(C{{H}_{2}})}_{6}}N{{H}_{2}}\]    

    B)  \[C{{H}_{3}}=CH-C(C{{H}_{3}})=C{{H}_{2}}\]

    C)  \[C{{H}_{2}}=C{{H}_{2}}\]

    D)  

    Correct Answer: A

    Solution :

                    Nylon-66 is a condensation polymer of hexamethylene diamine and adipic acid. \[nHOOCC{{H}_{2}}C{{H}_{2}}COOH+n{{H}_{2}}N{{(C{{H}_{2}})}_{6}}N{{H}_{2}}\xrightarrow{-{{H}_{2}}O}\]\[\underset{nylon-66}{\mathop{{{\left[ -\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-C{{H}_{2}}C{{H}_{2}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-NH-{{(C{{H}_{2}})}_{6}}-NH- \right]}_{n}}}}\,\]
