Explain : Chemical reactions of ethanol

Explanation

Chemical reactions (properties) of ethanol are as follows:
(1) Reaction of ethanol (alcohol) with sodium metal : Reaction of - OH group of ethanol with sodium metal produces sodium ethoxide and hydrogen gas.
`underset("Sodium")(2Na)+underset("Ethanol")(2CH_(3)CH_(2)OH)tounderset("Sodium ethoxide")(2CH_(3)CH_(2)O^(-)Na^(+))underset(" gas")underset(" Hydrogen")(+" "H_(2))`
( 2 ) Reaction of ethanol with concentrated sulphuric acid (Dehydration of alcohol) : When ethanol is heated with excess of concentrated sulphuric acid at 443 K, it forms ethene due to dehydration of ethanol.

Here, concentrated sulphuric acid acts as a dehydrating agent.
