Solution

a) Ethane reaction with chlorine in presence of sunlight to give chloroethane.
reaction of chloroethane with alkoholic KOH to give ethanol.
$C_{2} H_{6} + C l_{2}$ $\Rightarrow$ $C H_{3} C H_{2} C l$
$C_{2} H_{6} + a l c o h o l i c K O H$ $\Rightarrow$ $C H_{3} C H_{2} O H$

(b) When mixture of ethane and oxygen is passed through heated molybdenum oxide, the mixture is oxidized to Acetaldehyde.
$C_{2} H_{6} + O_{2}$ $\Rightarrow$ $C H_{3} C H O + H_{2} O$ | In presence of MoO

(c)Ethanol formed from ethane gets oxidized to acetic acid.
2 $C_{2} H_{6} + O_{2}$ $\Rightarrow$ 2 $C_{2} H_{5} O H$ |at 120 atm in presence of cu tubes at 475 K
$C_{2} H_{5} O H + O_{2}$ $\Rightarrow$ $C H_{3} C O O H + H_{2} O$ |Pt at 300 C
