A) $\phi\ MgBr + \left( C_{2}H_{5} \right)_{2}CO\ \overset{\rightarrow}{{\ \ \ H}_{2}O\ \ \ \ }$
B) [image:11_image213.emf]
C) $C_{2}H_{5}MgBr + \phi{COCH}_{2}{CH}_{3}\ \overset{\rightarrow}{{\ \ H}_{2}O\ \ \ }$
D) $\phi MgBr + C_{2}H_{5}{COCH}_{3}\ \overset{\rightarrow}{{\ \ H}_{2}O\ \ \ }$
Explanation
The correct answer is Option D: $\phi MgBr + C_{2}H_{5}{COCH}_{3}\ \overset{\rightarrow}{{\ \ H}_{2}O\ \ \ }$.
