A binary liquid solution of n-heptane and ethyl alcohol is prepared which of the following statements correctly represents the behaviour of this liquid solution?

Options

A. The solution formed is an ideal solution
B. The solution formed is a non - ideal solution with positive deviations from Raoult's law.
C. The solution formed is a non- ideal solution with negative deviations from Raoult's law
D. Normal-heptane exhibits postive deviations , whereas ethyl alcohol exhibits negative deviations from Raoult's law

Answer

B

Explanation

Intermolecular forces among molecules of n- heptane and ethyl alcohols are weaker than among hexane and among ethyl alcohols molecules,`:.`V.P. of solution is ,ore than V.P.of pure solvents.
