    A) Bakelite

    B) Teflon

    C) Polythene

    D) Perspex

    Correct Answer: B

    Solution :

               \[2CHC{{l}_{3}}\underset{Sb{{F}_{3}}}{\mathop{\xrightarrow{HF}}}\,2CH{{F}_{2}}Cl\underset{-2HCl}{\mathop{\xrightarrow{{{800}^{0}}C}}}\,\]   \[C{{F}_{2}}=C{{F}_{2}}\xrightarrow{\text{Polymari}}{{(-C{{F}_{2}}-C{{F}_{2}}-)}_{r}}\]
