    PVC is obtained by polymerization of

    A)                 \[C{{H}_{2}}=CH-C{{H}_{2}}-Cl\]               

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

    C)                 \[C{{H}_{3}}-Cl\]              

    D)                 \[C{{H}_{3}}-CHC{{l}_{2}}\]

    Correct Answer: B

    Solution :

              \[\underset{\text{Vinyl chloride}}{\mathop{n(C{{H}_{2}}=CH-Cl}}\,)\to \underset{\,\,\,\,\,\,\,\,\,\,(PVC)}{\mathop{{{(-C{{H}_{2}}-\underset{Cl\,\,}{\mathop{\underset{|\,\,\,\,\,}{\mathop{CH}}\,}}\,-)}_{n}}}}\,\]
