Question

Give equations for the reaction if
(i) Ethanol is heated with conc. H2SO4 at 443 K
(ii) Ethanol reacts with ethanoic acid in the presence of H2SO4
(iii) C2H6 is burnt in presence of O2
(iv) An ester reacts with a base.

Answer 1

Answer:

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 +
