Explanation:

\[\begin{array}{cc}
\ce{H3C}\phantom{......}\ce{CH3}\phantom{..................}\ce{O}\phantom{..........}\\
\backslash\phantom{......}/\phantom{......................}||\phantom{........}\\
\ce{C = C ->[(1) O3][(2) Zn dust H2O] \underset{Propanone}{2H3C - C - CH3}}\\
/\phantom{......}\backslash\phantom{...............................}\\
\ce{H3C}\phantom{....}\ce{CH3}\phantom{.............................}\end{array}\]
