उत्तर

When isopropyl alcohol is heated at 573 K in the presence of Cu, acetone is formed.

\[\begin{array}{cc}
\ce{CH3 - CH - CH3 ->[Cu/573K][Oxidation] CH3 - C - CH3}\\
\phantom{...}|\phantom{..........................}||\phantom{...}\\
\ce{\underset{\text{Isopropyl alcohol}}{OH}\phantom{..................}\underset{\text{Acetone}}{O}\phantom{...}}\\
\end{array}\]
