Write down the properties of matter.

You have a mixture of three liquids $A$,$B$,and $C$. There is a large difference in the boiling points of $A$ and the rest of the two liquids,i.e.,$B$ and $C$. The boiling points of liquids $B$ and $C$ are quite close. Liquid $A$ boils at a higher temperature than $B$ and $C$,and the boiling point of $B$ is lower than that of $C$. How will you separate the components of the mixture?

$A$ miscible mixture of $C_6H_6 + CHCl_3$ can be separated by
