(b) one mole of ethene with one mole of chlorine gas:

(c) ethyne from 1, 2 – dibromoethane.

(d) Preparation of ethane from sodium propionate.

$\underset{\text{sodium propionate}}{\text{C}\text{H}$3\text{-C}\text{H}2\text{.COONa}} + \underset{\text{sodalime}}{\text{NaOH}} \xrightarrow[\Delta]{\text{CaO}} \underset{\text{ethane}}{\text{C}2\text{H}6} + \text{Na}2\text{CO}3

(e) Preparation of ethanol from monochloroethane and aq. sodium hydroxide.

$\underset{\text{ monochloroethane}}{\text{C}$2\text{H}5\text{-Cl}} + \underset{ \text{ aq. sodium hydroxide}}{\text{NaOH[aq]}} \xrightarrow{\text{boil}} \underset{ \text{ Ethanol [ethyl alcohol]} }{\text{C}2\text{H}5\text{-OH}} + \text{NaCl}\
