In steam distillation of aniline, function of steam is `:`

A

to increase the vapour pressure of the liquid to be distilled

B

to decrease the vapour pressure of the liquid to be distilled

C

to carry vapours of the liquid with it, it has nothing to do with the vapour pressure of the liquid

D

to dissolve the liquid due to high temperature.

Text Solution

Verified by Experts

The correct Answer is:
B
In steam distillation of aniline, steam decreases vapour pressure of the liquid which in turn starts boiling below its usual boiling point. Hence steam distillation is considered analogous to distillation under reduced pressure.
