Write balanced equation for preparation of:

(i) ethane from sodium propionate.

(ii) ethanol from monochloroethane and aq. sodium hydroxide.

(i) 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

(ii) 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}\
