Question

Two liquids (A) and (B) can be separated by the method of fractional distillation. The boiling point of liquid (A) is less than boiling point of liquid (B). Which of the liquids do you expect to come out first in the distillate? Explain.

Answer 1

The liquid (A) is expected to come out first in the distillate. On boiling the vapours of lower boiling component are formed first. The vapours are condensed to get the liquid in a receiver.
