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

Options

  1. Anegative deviation from Raoult's law
  2. Bpositive deviation from Raoult's law
  3. Cno deviation from Raoult's law
  4. Dpositive or negative deviation from Raoult's law depending upon the composition

Correct answer

A. negative deviation from Raoult's law

Step-by-step solution

Solutions boils at relatively higher temperature, vapour pressure of solution is less. Hence, it shows negative deviation from Raoult's law.
