Question

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

Answer 1

(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:

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