Question

Write equations for the reaction of ethanol (C2H5OH) with-
i)Sodium Metal
ii)Conc. H2SO4
iii)Ethanoic acid in presence of Conc. H2SO4

Answer 1

1) 2c2h5oh+2na=2c2h5ona+H2
2)c2h5oh+h2so4=c2h4+H2o+H2so4
3) c2h5oh+CH3COOH=CH3COOCH2CH3+H2O

Answer 2

Reactions of Ethanol

Explanation:

1) Ethanol reacts with sodium to form sodium ethoxide and hydrogen gas.

2CH3CH2OH + 2Na --> 2CH3CH2-ONa + H2

2) When Ethanol is heated with concentrate sulphuric acid, it forms Ethene along with water. Here H2SO4 is a catalyst and it acts as a dehydrating agent.

CH3CH2OH + H2SO4 ---> CH2=CH2 + H2O

3) Ethanoic acid reacts with ethanol in the presence of concentrated sulphuric acid as a catalyst to produce the ester, ethyl ethanoate.

CH3CH2OH + CH3COOH  --> CH3COOCH2CH3 + H2O
