Identify the balanced chemical reaction of sodium with ethanol.


Options:
A .   2Na + CH3CH2OH 2CH3CHO + 2NaH
B .   2Na + CH3CH2OH 2CH3CH2Na + H2O
C .   2Na + 2CH3CH2OH 2CH3CH2ONa + H2
D .   2Na + CH3CH2OH CH3CH2ONa + H2
Answer: Option C
:
C
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) 2CH3CH2ONa(aq) + H2(g)
