    Complete the following chemical equations:
    (i) \[\mathbf{C}{{\mathbf{H}}_{\mathbf{3}}}\mathbf{+COO}{{\mathbf{C}}_{\mathbf{2}}}{{\mathbf{H}}_{\mathbf{5}}}\mathbf{+NaOH}\to \]
    (ii) \[\mathbf{C}{{\mathbf{H}}_{\mathbf{3}}}\mathbf{COOH}+\mathbf{NaOH}\to \]
    (iii) \[{{\mathbf{C}}_{\mathbf{2}}}{{\mathbf{H}}_{\mathbf{5}}}\mathbf{OH}+\mathbf{C}{{\mathbf{H}}_{\mathbf{3}}}\mathbf{COOH}\xrightarrow{Conc.{{\mathbf{H}}_{\mathbf{2}}}\mathbf{S}{{\mathbf{O}}_{\mathbf{4}}}}\]
     

    Answer:

    (i) \[C{{H}_{3}}COO{{C}_{2}}{{H}_{5}}+NaOH\xrightarrow{{{H}_{2}}O}\] \[{{C}_{2}}{{H}_{5}}OH+C{{H}_{3}}COONa\]
    (ii) \[C{{H}_{3}}COOH+NaOH\to C{{H}_{3}}COONa+\mathrm{ }{{H}_{2}}O\]
    (iii) \[{{C}_{2}}{{H}_{5}}OH+C{{H}_{3}}COOH\to C{{H}_{3}}COO{{C}_{2}}{{H}_{5}}+{{H}_{2}}O\]
