    The monomer of teflon is:

    A) \[CHF=C{{H}_{2}}\]                        

    B) \[C{{F}_{2}}=C{{F}_{2}}\]

    C) \[CHCl=CHCl\]  

    D) \[CHF=CHCl\]

    Correct Answer: B

    Solution :

    Tetrafluoroethene is the monomer of teflon. \[nC{{F}_{2}}\equiv C{{F}_{2}}\xrightarrow{Polymerisation}\underset{Teflon}{\mathop{-(C{{F}_{2}}-C{{F}_{2}}){{-}_{n}}}}\,\]
