(B) : The solution containing n-heptane and ethanol shows non-ideal behaviour with positive deviation from Raoult’s law. This is because the ethanol molecules are held together by strong H-bonds, however the forces between n-heptane and ethanol are not very strong, as a result they easily vapourise showing higher vapour presure than expected.

Understanding the Solution Behavior
When mixing n-heptane and ethanol, the behavior of the resulting binary liquid solution can be analyzed through Raoult's Law and the concept of ideal versus non-ideal solutions.
Raoult's Law Overview
- Raoult's Law states that the partial vapor pressure of each component in an ideal solution is proportional to its mole fraction.
- Deviations from this law occur in real solutions due to interactions between different molecules.
Nature of n-Heptane and Ethanol
- n-Heptane is a non-polar hydrocarbon, while ethanol is a polar molecule with hydrogen bonding capabilities.
- When mixed, these two solvents exhibit different strengths of intermolecular interactions.
Deviation from Raoult's Law
- The solution shows positive deviation from Raoult's Law, meaning that the vapor pressure of the solution is higher than expected.
- This is primarily due to the weaker interactions between n-heptane and ethanol compared to the stronger hydrogen bonding interactions present in pure ethanol or pure n-heptane.
Consequences of Positive Deviation
- The mixing of a polar and non-polar solvent results in a disruption of the strong intermolecular forces, leading to increased vapor pressure.
- This behavior indicates non-ideal characteristics, where the solution does not follow Raoult's Law strictly.
Conclusion
- The correct answer is option 'B': The solution is non-ideal, showing positive deviation from Raoult's Law.
- This highlights the importance of understanding molecular interactions in predicting solution behavior accurately.
