Fractional distillation is performed on which of the following?
Open in App
Solution
The correct option is C liquid air
The fractional distillation process is used for the separation of components of a mixture containing two or more miscible liquids when the difference in their boiling points is less than 25K.
Air is a homogeneous mixture of gases and can be separated into its components by fractional distillation in its liquid form only. It is compressed by increasing the pressure and is then cooled by decreasing the temperature to get liquid air. This liquid air is allowed to warm up slowly in a fractional distillation column, where gases get separated at different heights depending upon their boiling points.
