Solution
\[\begin{array}{cc}
\phantom{..............................}\ce{OH}\phantom{................................}\ce{O}\phantom{....}\\
\phantom{...........................}|\phantom{...................................}||\phantom{.}\\
\ce{\underset{(Propanal)}{CH3CH2CHO} ->[(i) CH3MgBr][(ii) H^+/H2O] \underset{(Butan-2-ol)}{CH3 - CH2 - CH - CH3} ->[Conc. HNO3][(O)] \underset{(2-Butanone)}{CH3 - CH2 - C - CH3} + H2O}
\end{array}\]
