    Name the products in the following reaction: \[{{C}_{6}}{{H}_{5}}C{{H}_{2}}C{{O}_{2}}C{{H}_{3}}\xrightarrow[(ii){{H}^{+}}]{(i)C{{H}_{3}}MgBr(excess)}?\]

    A)

    B)

    C)            

    D)

    Correct Answer: D

    Solution :

    \[{{C}_{6}}{{H}_{5}}C{{H}_{2}}-\underset{\underset{O{{C}_{2}}{{H}_{5}}}{\mathop{|}}\,}{\mathop{C}}\,=O\xrightarrow[(ii)\,\,{{H}_{2}}O/{{H}^{+}}]{\begin{smallmatrix}  (i)\,\,2moles\,\,of \\  C{{H}_{3}}MgI \end{smallmatrix}}\]\[{{C}_{6}}{{H}_{5}}-C{{H}_{2}}-\underset{\underset{OH}{\mathop{|}}\,}{\mathop{\overset{\overset{C{{H}_{3}}}{\mathop{|}}\,}{\mathop{C}}\,}}\,-C{{H}_{3}}\]
