Compreshension-II
In non-ideal solutions, at one of the intermediate compostions, the total vapour pressure is highest and the boiling point is lowest. At this point, the composition of the liquid and vapour phase is same. So, if liquid mixture vapouriese at this point and vapours are condensed, teh condensate contains same compositon as present in original liquid mixture. it means at this point liquid behaves like a pure liquid and is called an Azeotropic mixture.
Which of the following cannot form low boiling point azeotrope ?

A

n-heptane & n-hexane

B

Acetone & aniline

C

Both (1) & (2)

D

`CHCl_(3) & C_(2)H_(5)OH`
