Which will form maximum boiling point azeotrope

Question

Which will form maximum boiling point azeotrope (A) HNO 3+ H 2 O solution (B) C 2 H 5 OH + H 2 O solution (C) C 6 H 6+ C 6 H 5 CH 3 solution (D) None of these

Tardigrade Admin · Accepted Answer

The solutions (liquid mixture) which boils at constant temperature and can distil as such without any change in composition are called azeotropes.
Solution of

H N O_{3}

and

H_{2} O

will form maximum boiling point azeotrope. Maximum boiling azeotropes show negative deviation from Raoult's law.

Boiling point of the azeotrope of these two solutions is

393.5 K

Q. Which will form maximum boiling point azeotrope
