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

Ethenol forms H-bonding where as n-heptane does not. On mixing n-heptane & ethanol H-bonding of ethanol breaks, so it will be non-deal with positive deviation.
