Chemical Properties of Ethanol

1. Combustion – They burn in oxygen to form water and carbon (iv) oxide.
C2H6OH(aq) + 3O2(g)  →  2CO2(g) + 3H2O(L)

2. It reacts with sodium or potassium to liberate hydrogen gas.
2Na(s) + 2C2H6OH(aq)  →  2CH6ON(aq) + H2(g)

3. Oxidation – It is oxidized partially into alkanol and completely into ethanoic acid in the presence of oxidizing agent like KMnO4 or KCr2O7

C2H5OH(aq)  →  CH3CHO(g) + H2O(L)

CH2CHO(g)  →  CH3COOH(aq)

4. Esterification – It is the reaction between alkanol and alkanoic acid to form alkanoate and water.
C2H5OH(aq) + CH3COOH(aq) →  CH3COOC2H5(aq)

5. Dehydration – It is dehydrated in the presence of Conc. H2SO4 at 1700c to form ethene.
CH2H5OH(aq)  →  C2H4(g)
