Q. An azeotropic mixture of two liquids has boiling point lower than either of them, when it
A) Shows a negative deviation from Raoult’s law
B) Shows no deviation from Raoult’s law
C) Shows positive deviation from Raoult’s law
D) Is saturated
Explanation
(c)
(i)Azeotropic mixtures having boiling point less than either of the two pure components show positive deviation from Raoult’s law.
(ii) Azeotropic mixtures having boiling point more than either of two pure components show negative deviation from Raoult’s law.
