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?

Answer»

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.
The solution FORMED is an ideal solution.

Solution :For this solution intermolecular interactions between n-heptane and ethanol are weaker than n-heptane-nheptane & ethanol-ethanol interactions HENCE the solution of n-heptane and ethanol is non-ideal and shows positive deviation from Raoult's law.
