Distinguish between the saturated hydrocarbon ethane and the unsaturated hydrocarbon ethene by drawing their structural formulae.

Open in App

Solution

Saturated hydrocarbon ethane:

Hydrocarbons having only single bonds are known as an alkane. These are saturated hydrocarbons. The general formula of an alkane is $C_{n} H_{2 n + 2}$ .

$H_{3} C - C H_{3}$ (Ethane)

Unsaturated hydrocarbon ethene:

Hydrocarbons having at least one double bond are known as an alkene. The general formula of an alkene is $C_{n} H_{2 n}$ .

$H_{2} C = C H_{2}$ (Ethene)
