A) \[C{{H}_{3}}MgI\] and \[C{{H}_{3}}COC{{H}_{3}}\]
B) \[C{{H}_{3}}MgI\] and \[{{C}_{2}}{{H}_{5}}OH\]
C) \[C{{H}_{3}}MgI\] and \[C{{H}_{3}}COO{{C}_{2}}{{H}_{5}}\]
D) \[C{{H}_{3}}MgI\] and \[HCOO{{C}_{2}}{{H}_{5}}\]
Correct Answer: C
Solution :
\[\underset{\text{Ethyl methyl ester}}{\mathop{C{{H}_{3}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-O{{C}_{2}}{{H}_{5}}}}\,+C{{H}_{3}}MgI\to C{{H}_{3}}-\underset{C{{H}_{3}}\ \ \ \ \ \ \ \ \,}{\overset{O-MgI\ \ \ \ }{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,-O{{C}_{2}}{{H}_{5}}}}}\,\]\[\xrightarrow{\text{Hydrolysis}}C{{H}_{3}}-\underset{C{{H}_{3}}\,\,}{\overset{OH\ \,}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,-O}}}\,{{C}_{2}}{{H}_{5}}\xrightarrow{+Mg<\begin{matrix} Br\ \\ OH \\ \end{matrix}}\]\[\underset{\text{Acetone}}{\mathop{\begin{matrix} C{{H}_{3}} \\ C{{H}_{3}} \\ \end{matrix}>C=O}}\,+\underset{\text{Ethyl alcohol}}{\mathop{{{C}_{2}}{{H}_{5}}OH}}\,\]
