Question

Benzene and chloroform are separated by:

• A. sublimation
• B. filtration
• C. distillation
• D. crystallization

Answer 1

The correct option is C distillation

The boiling point of benzene is ${80}^{0}C$ & that of chloroform is ${61.2}^{0}C$. If we distil the mixture chloroform will boil & collect first. By using a water / oil bath at ${62-65}^{0}C$, chloroform can be vaporized, condensed & gets collected. If the temperature is near to ${80}^{0}C$, benzene gets vapourized & condensed.
