Solution

The saturated and unsaturated hydrocarbons are distinguished by the alkaline solution of the potassium permanganate chemical test.
The unsaturated alkene reacts with an alkaline solution of Potassium permanganate $({KMnO}_{4})$ changes the color of the solution.
The vapor density of Ethene $(C_{2} H_{4})$ is $14$ and its decolorizes alkaline solution of Potassium permanganate.
The chemical reaction of Ethene with alkaline solution of Potassium permanganate is written as:
${CH}_{2} = {CH}_{2} \overset{alk . {KMnO}_{4}}{\to} (OH) {CH}_{2} - {CH}_{2} (OH) (Ethene) Ethane - 1, 2 - diol$
