A binary liquid solution is prepared by mixing n-heptane and ethanol. Which one of the following statements is correct regarding the behaviour of the solution?

Options

A. The solution is non-ideal, showing-ve deviation from Raoult's law
B. n-heptane shows+ve deviation while ethanol shows-ve deviation from Raoul's law
C. The solution formed is an idela solution.
D. The solution is non-idela showing +ve deviation from Raoult's law

Answer

D

Explanation

(A) n-heptone: Non polar
(B) Ethanol: Polar
`F_(A-B) lt F_(A-A') F_(B-B) rArr +` deviation
