An organic compound ‘A’ is an essential constituent of wine and beer. Oxidation of ‘A’ yields an organic acid ‘B’ which is present in vinegar. Name the compounds ‘A’ and ‘B’ and write their structural formula. What happens when ‘A’ and ‘B’ react in the presence of an acid catalyst? Write the chemical equation for the reaction.

'A' is ethanol (C2H5OH) which is essential constituent of wine and beer and 'B' is acetic acid (CH3COOH) which is present in vinegar.
When 'A' and 'B' react in the presence of an acid catalyst, ethyl ethanoate is formed.
CH3COOH(l)('B') + C2H5OH(l)('A') + conc. H2SO4 → CH3COOC2H5(l) + H2O(l)
