    State the monomer of Teflon

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

    B)  \[C{{H}_{2}}=CH\cdot Cl\]

    C)  \[C{{H}_{2}}=\underset{Cl}{\mathop{\underset{|}{\mathop{C}}\,}}\,-CH=C{{H}_{2}}\]

    D)  \[C{{H}_{2}}=CH\cdot CN\]

    Correct Answer: A

    Solution :

                                    Tetra fluoroethene is a monomer of Teflon. \[nC{{F}_{2}}=C{{F}_{2}}\xrightarrow{Polymerisation}\underset{teflon}{\mathop{-{{[C{{F}_{2}}-C{{F}_{2}}]}_{n}}-}}\,\]
