Question

write chemical equations of represent what happen when:
(a) ethanol burns in air
(b) ethanol reacts with sodium metal
(c) ethanol is heated with alkaline kmno4
(d)ethanol is heated with ethanoic acid in pressure of few drops of concentrated sulphuric acid
(e) ethanol is heated with at 443 k excess of concentrated H2SO4

Answer 1

a)C2H5OH + 3O2 ----> 2CO2 + 3H2O + Heat + Light

b) C2H5OH + 2Na----> 2C2H5ONa + H2

c) C2H5OH ----> CH3COOH + H2O

d) C2H5OH + CH3COOH ---> CH3COOC2H5 + H2O

e)C2H5OH+H2SO4 ----> C2H4+H2O

Answer 2

a) C2H5OH + 3O2 -----> 2CO2 + 3H2O.
b)2C2H5OH + 2Na = 2C2H5ONa + H2
c) CH3-CH2-OH + KMnO4 → CH3-COOH
d)C2H5OH + C2H5COOH ——— > C2H5COOC2H5 + H2O
e) CH3-CH2-OH → (H2SO4 + heat) → CH2=CH2 + H2O
