    \[C{{H}_{3}}COOH\] is reacted with \[CH\equiv CH\] in presence of \[H{{g}^{2+}}\], the product is:

    A)  \[\underset{\begin{smallmatrix}  | \\  C{{H}_{2}}(OOC{{H}_{3}}) \end{smallmatrix}}{\mathop{C}}\,{{H}_{2}}(OOCC{{H}_{3}})\]

    B)  \[\overset{\begin{smallmatrix}  C{{H}_{3}} \\  | \end{smallmatrix}}{\mathop{C}}\,{{H}_{2}}-(OOC-C{{H}_{3}})\]

    C)  \[\overset{\begin{smallmatrix}  C{{H}_{3}} \\  | \end{smallmatrix}}{\mathop{C}}\,H{{(O\,OC-C{{H}_{3}})}_{2}}\]

    D)  none of the above

    Correct Answer: C

    Solution :

    \[CH\equiv CH+C{{H}_{3}}COOH\xrightarrow{[H{{g}^{2+}}]}\] \[\underset{vinyl\,\,\,ace\operatorname{tate}}{\mathop{{{H}_{2}}C=CH-OCOC{{H}_{3}}}}\,\] \[{{\downarrow }^{C{{H}_{3}}COOH}}\] \[\underset{ethyledine\text{ }acetate}{\mathop{C{{H}_{3}}CH{{(O-CO{{H}_{3}})}_{2}}}}\,\] This reaction is an example of addition reaction.
