Alcohols contain a hydrocarbon chain, so they burn in air. The products are carbon dioxide and water.
Alcohols react with sodium. When ethanol reacts with soduim, the products are soduim ethoxide and hydrogen.
Water reacts with sodium in the same way; the products are sodium hydroxide and hydrogen.
The reactions are similar because both water and ethanol contain an -OH group. When they react an O-H bond breaks.
Sodium ethoxide and sodium hydroxide are both salts.
Alkanes do not react with sodium. This is because alkanes have no -OH group. Their C-C and C-H bonds are unreactive.
