Describe the simple distillation method for the purification of liquid compounds.

(N/A) Principle: Simple distillation is used to purify liquids that boil without decomposition and have sufficient difference in their boiling points.
$(B)$ Procedure: The liquid mixture is taken in a round-bottom flask. The flask is fitted with a thermometer,a condenser,and a water inlet/outlet. $A$ conical flask is placed at the open end of the condenser to collect the distillate.
The mixture is heated carefully. The component with the lower boiling point vaporizes first. These vapours pass through the condenser,where they are cooled by circulating cold water,and condense back into a pure liquid,which is collected in the receiver (conical flask).
$(C)$ Example: $A$ mixture of chloroform (boiling point $334 \ K$) and aniline (boiling point $457 \ K$) can be easily separated by this technique.
