Solution

The correct option is C 2Na + 2CH3CH2OH 2CH3CH2ONa + H2
The reaction between sodium and alcohol is a metal-acid reaction. Metals generally liberate hydrogen on reacting with acids.

Ethanol reacts with sodium leading to the evolution of hydrogen and sodium ethoxide. The reaction occurs as follows:

2Na(s) + 2CH3CH2OH(aq) ā†’2CH3CH2ONa(aq) + H2(g)
