Solution

Ethyl alcohol gives hydrogen on reaction with sodium metal. On oxidation with PCC ethanol will form acetaldehyde (C2H4O).

\[\ce{\underset{\text{Ethyl alcohol}}{2CH3 - CH2 - OH} ->[2Na] \underset{\text{Sodium ethoxide}}{2CH3 - CH2 - O- Na+} + {H_{2(g)}} ^}\]

\[\ce{\underset{\text{Ethyl alcohol}}{CH3 - CH2 - OH} ->[{[O]}][PCC] \underset{\ce{Acetaldehyde(C2H4O)}}{CH3 - CHO} + H2O}\]
