(a) An acid 'X' and an alcohol 'Y' react with each other in the presence of an acid catalyst to form a sweet smelling substance 'Z'. Identify 'X', 'Y' and 'Z'. Write the chemical equation for the reaction involved and name it. The substance 'Z' on treatment with sodium hydroxide produces back the alcohol 'Y' and sodium ethanoate. Write the chemical equation for the reaction involved and name it, giving justification for the name.
Solution
(a) 'X' – CH3COOH / Ethanoic Acid / Acetic Acid
'Y' – C2H5OH / Ethanol
'Z' – CH3COOC2H5 / Ethyl Ethanoate
CH3COOH + C2H5OH $\xrightarrow{\text{Acid catlyst}}$ CH3COOC2H5 + H2O
Esterification Reaction
CH3COOC2H5 $\xrightarrow{\text{NaOH}}$ C2H5OH + CH3COONa
Saponification Reaction
It is used in the preparation of soap.
