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 is non-ideal, showing +ve deviation form Raoult's Law
• B. The solution is non-ideal, showing -ve deviation from Raoult's Law
• C. n-heptane shows +ve deviation while ethanol shows - ve deviation from Raoult's Law
• D. The solution formed is an ideal solution

Answer 1

The correct option is A

The solution is non-ideal, showing +ve deviation form Raoult's Law

n-Heptane and ethanol show positive deviation from Raoult's law, The forces of attraction between n-heptane and ethanol will be less than their individual molecules. They form a non-ideal solution.
