    The monomeric unit of orlon molecule is

    A)  \[C{{H}_{2}}=CH-Cl\]

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

    C)  \[C{{H}_{2}}-CH-CN\]

    D)  \[{{C}_{6}}{{H}_{5}}-CH=C{{H}_{2}}\]

    Correct Answer: C

    Solution :

     Vinyl cyanide (acrylonitrile),\[C{{H}_{2}}=CHCN\] is  the monomeric unit of orlon molecule. \[\underset{Vinyl\,cyanide}{\mathop{nC{{H}_{2}}=CHCN}}\,\xrightarrow{{}}\underset{\begin{smallmatrix}  Polyacrylonitrile \\  \,\,\,\,\,\,\,\,\,or\,orlon \end{smallmatrix}}{\mathop{[-C{{H}_{2}}-CHCN-n]}}\,\]
