    Correct Answer: C

    Solution :

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