Answer :
There are three processes involved in the conversion of ethane to ethanoic acid.
In first process, on the chlorination of the ethane in the presence of the sunlight or in the presence of U.V light, ethane converted into ethyl chloride.
In the second process, ethyl chloride react with the aqueous potassium hydroxide to give ethanol.
In the third process, ethanol react with an oxidizing agent (Alkaline potassium permanganate) to give ethanoic acid.
The reaction are shown below.
