Question

Alcohal is more volatile than water because : 

(a) its boiling point is lower than water 

(b) it is an organic compound 

(c) its freezing point is lower than water 

(d) its vapour pressure is 2.5 times greater than water

Answer 1

Correct option (a) its boiling point is lower than water

Explanation:

At boiling point, all the substances are converted into vapour. Because boiling point of alcohal is lower than boiling point of water, so it will vaporise earlier as compared to water, i.e., alcohal is more volatile than water.
