Answer 1

\[\begin{array}{cc}
\phantom{........}\ce{O}\phantom{..........................}\ce{OMgI}\phantom{..................}\ce{O}\phantom{..............}\ce{I}\phantom{}\\
\phantom{.......}||\phantom{.............................}|\phantom{.....................}||\phantom{............}/\\
\ce{\underset{\text{Acetyl chloride}}{CH3 - C - Cl}+ CH3Mgl -> CH3 - C - Cl ->[H2O/H+] \underset{\text{Acetone}}{CH3 - C - CH3} + Mg}\\
\phantom{......................................}|\phantom{...................................}\backslash\\
\phantom{......................................}\ce{CH3}\phantom{...................................}\ce{Cl}
\end{array}\]
