In steam distillation of toluene, the pressure of toluene in vapour is
  1. A
    equal to pressure of barometer
  2. B
    Less than pressure of barometer
  3. C
    equal to vapour pressure of toluene in simple distillation
  4. D
    more than vapour pressure of toluene in simple distillation.
View written solutionFree

Correct answer: B

In steam distillation of toluene, the pressure of toluene in vapour is less than pressure of barometer, because it is carried out when a solid or liquid is insoluble in water and is volatile with steam but the impurities are non-volatile.
