Question

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 ?

• 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 1

Answer: (B)

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