    The monomer of P.V.C. is:

    A)  \[C{{H}_{3}}-CH=CH-Cl\]

    B)  \[C{{H}_{2}}=CH\cdot Cl\]

    C)  \[CH(CN)=CHC{{H}_{3}}\]

    D)  None of the above

    Correct Answer: B

    Solution :

    P.V.C. (poly vinyl chloride) is an important polymer. Which is used in making pipes, soles, cables etc. Its monomer is vinyl chloride. \[\underset{Vinyl\,chloride}{\mathop{nC{{H}_{2}}==CH\cdot Cl}}\,\xrightarrow{Polymerisation}\] \[\underset{P.V.C}{\mathop{{{\left[ --C{{H}_{2}}--\overset{Cl}{\mathop{\overset{|}{\mathop{CH}}\,}}\,-- \right]}_{n}}}}\,\]
