    In the following reaction 'A' is                 \[\begin{align}   & {{C}_{2}}{{H}_{5}}MgBr+{{H}_{2}}C-C{{H}_{2}}\xrightarrow{{{H}_{2}}O}A \\  & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\overset{\backslash /}{\mathop{O}}\, \\ \end{align}\] [MP PET 1994; CBSE PMT 1998]

    A)                 \[{{C}_{2}}{{H}_{5}}C{{H}_{2}}CHO\]      

    B)                 \[{{C}_{2}}{{H}_{5}}C{{H}_{2}}C{{H}_{2}}OH\]

    C)                 \[{{C}_{2}}{{H}_{5}}C{{H}_{2}}OH\]         

    D)                 \[{{C}_{2}}{{H}_{5}}CHO\]

    Correct Answer: B

    Solution :

               \[{{C}_{2}}{{H}_{5}}MgBr+\underset{\overset{\,}{\mathop{\,\overset{\backslash /}{\mathop{O}}\,}}\,}{\mathop{{{H}_{2}}C-C{{H}_{2}}}}\,\xrightarrow{{{H}_{2}}O}\]\[\underset{n\text{-butyl}\,\text{alcohol}}{\mathop{\underset{(A)}{\mathop{{{C}_{2}}{{H}_{5}}C{{H}_{2}}C{{H}_{2}}OH}}\,}}\,+MgBr(OH)\]
