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 non-ideal.
B. The solution is non-ideal showing positive deviations from Raoult's law
C. The solution is non-ideal showing negative deviations from Raoult's law.
D. n-heptane shows positive while ethanol shows negative deviations from Raoult's law.

Answer

B

Explanation

n-Heptane and ethanol form non-ideal solution and give a positive deviation as n-heptane-n-heptane intermolecular interaction is very poor as compared to ethanol-ethanol (hydrogen bonding) intermolecular interaction.
