319474 A solution of two liquids boils at a temperature more than the boiling point of either of them. Hence, the binary solution shows

1 negative deviation from Raoult’s law
2 positive deviation from Raoult’s law
3 no deviation from Raoult’s law
4 positive or negative deviation from Raoult’s law depending upon the composition.
