The raw material used in nylon-6 is

A)  adipic acid         

B)  phthalic acid

C)  ethylene glycol               

D)  caprolactum

Correct Answer: D

Solution :

                 Caprolactum is a monomer of nylon-6. \[\xrightarrow[\text{heat}]{{{\text{H}}_{\text{2}}}\text{O}}\underset{\begin{smallmatrix}  \text{amino}\,\text{caproic} \\  \text{acid} \end{smallmatrix}}{\mathop{{{H}_{2}}N-{{(-C{{H}_{2}})}_{5}}-COOH}}\,\] \[\xrightarrow[-{{H}_{2}}O]{Heat}\underset{nylon\,-6}{\mathop{{{\left[ -NH-{{(C{{H}_{2}})}_{5}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,- \right]}_{n}}}}\,\]
