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 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.
