प्रश्न
An organic compound gives hydrogen on reaction with sodium metal. It forms an aldehyde with molecular formula C2H4O on oxidation with pyridinium chlorochromate. Give the chemical equations in support of these observations.
उत्तर
Ethyl alcohol gives hydrogen on reaction with sodium metal. On oxidation with PCC ethanol will form acetaldehyde (C2H4O).
\[\ce{\underset{\text{Ethyl alcohol}}{2CH3 - CH2 - OH} ->[2Na] \underset{\text{Sodium ethoxide}}{2CH3 - CH2 - O- Na+} + {H_{2(g)}} ^}\]
\[\ce{\underset{\text{Ethyl alcohol}}{CH3 - CH2 - OH} ->[{[O]}][PCC] \underset{\ce{Acetaldehyde(C2H4O)}}{CH3 - CHO} + H2O}\]
