The interactions between n -heptane and ethanol are weaker than that in pure components

Q. 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 ?

The solution formed is an ideal solution

The solution is non-ideal, showing +ve deviation from Raoult’s law

The solution is non-ideal, showing -ve deviation from Raoult’s law

n-heptane shows +ve deviation while ethanol shows -ve deviation from Raoult’s law
