    When ethanol reacts with ethanoic acid in the presence of cone. \[{{\mathbf{H}}_{\mathbf{2}}}\mathbf{S}{{\mathbf{O}}_{\mathbf{4}}},\] a substance with fruity smell is produced. Answer the following:
    (i) State the class of compounds to which the fruity smelling compounds belong. Write the chemical equation for the reaction and write the chemical name of the product formed.
    (ii) State the role of cone. \[{{H}_{2}}S{{O}_{4}}\] in this reaction.

    Answer:

    (i) Ester
                \[C{{H}_{3}}COOH+C{{H}_{3}}C{{H}_{2}}OH\xrightarrow[{{H}_{2}}S{{O}_{4}}]{Conc.}C{{H}_{3}}COOC{{H}_{2}}C{{H}_{3}}+{{H}_{2}}O\]
    (ii) Cone. \[{{H}_{2}}S{{O}_{4}}\] acts as a dehydrating agent.
