Write the equation for following reaction:
(i) Bromoethane and an aqueous solution of hydroxide.
(ii) Calcium carbide and water.
(iii) Ethene and water (steam).

(i) The reaction between bromoethane and an aqueous solution of hydroxide is given as follows:

$\underset{\mathrm{Bromoethane}}{{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{Br}}+\underset{\mathrm{aqueous}}{\mathrm{KOH}}\to \underset{\mathrm{Ethanol}}{{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}}+\mathrm{KBr}$

(ii) The reaction between calcium carbide and water is:

$\underset{\mathrm{Calcium}\mathrm{carbide}}{{\mathrm{CaC}}_2}+{\mathrm{H}}_2\mathrm{O}\to \underset{\mathrm{Ethyne}}{{\mathrm{C}}_2{\mathrm{H}}_2}+\mathrm{Ca}{\left(\mathrm{OH}\right)}_2$

(iii) The reaction between ethene and water (steam) is given by the equation:

$\underset{}{\underset{\mathrm{Ethene}}{{\mathrm{C}}_2{\mathrm{H}}_4}+{\mathrm{H}}_2\mathrm{O}\to \underset{\mathrm{Ethanol}}{{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}}}$
