Marks: +1, -0

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.

Solution:

For this solution intermolecular interactions between

n

-heptane and ethanol aare weaker than

n

-heptane

-n

- heptane

\&

ethanol-ethanol interactions hence the solution of

n

-heptane and ethanol is non-ideal and shows positive deviation from Raoult's law.
