During the separation of acetone from water by fractional distillation, the following steps are carried out. Arrange the following in a proper sequence.
(1) Water remains in the distillation flask.
(2) The acetone-water mixture is taken in a distillation flask and the flask is heated at a temperature equal to or more than the boiling point of acetone but less than that of water.
(3) As the vapours pass through the fractionating column, they get condensed and the liquid formed is collected in the receiver.
(4) When the mixture in the flask is subjected to slow heating, acetone, being more volatile than water, gets vaporised first.

Options

A. 2 4 3 1
B. 2 4 1 3
C. 3 1 2 4
D. 3 1 4 2

Explanation

(i) The acetone-water mixture is passed into the distillation flask and the flask is heated at a temperature equal to or more than the boiling point of acetone but less than that of water.
(ii) When the mixture in the flask is subjected to
slow heating, acetone, being more volatile than
water, gets vaporised first.
(iii) As the vapours pass through the fractionating column, they get condensed and the liquid formed is collected in the receiver.
(iv) Water remains in the distillation flask.
