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

Answer

B

Explanation

The interactions between n-heptane and ethanol are weaker than that in pure components as n- heptane is non-polar and ethanol is polar.
