    In the following reaction product will be \[nC{{H}_{2}}=CH-O-\underset{\begin{smallmatrix}  || \\  O \end{smallmatrix}}{\mathop{C}}\,-C{{H}_{3}}\xrightarrow[{}]{Polymerization}Product\]

    A)  polyvinyl acetate 

    B)  polyacrylonitrile

    C)  vinyl acetate      

    D)  acrylonitrile

    Correct Answer: A

    Solution :

     The molecules of vinyl acetate form polyvinyl acetate on polymerization. \[nC{{H}_{2}}=CH-O-\underset{\begin{smallmatrix}  || \\  O \end{smallmatrix}}{\mathop{C}}\,-C{{H}_{3}}\xrightarrow[{}]{Polymerization}\] \[\underset{polyvinyl\text{ }acetate}{\mathop{-(C{{H}_{2}}\underset{\begin{smallmatrix}  | \\  OCOC{{H}_{3}} \end{smallmatrix}}{\mathop{-CH){{-}_{n}}}}\,}}\,\]
