Explain with diagrams the process used to separate Benzene from a mixture of benzene [b.p. 80°C] & toluene [b.p. 110°C].

Fractional distillation can be used to separate benzene from a mixture of benzene [b.p. 80°C] & toluene [b.p. 110°C]

Process — Mixture is kept in a distillation flask 'X' with a fractionating column. The flask is then heated as shown and the mixture evaporates and later condenses.

Higher boiling point liquid [toluene] remains in the flask X, after condensation.

Lower boiling point liquid [benzene] collects in the receiver Y, after condensation in Leibigs condenser.
