$\text{Hint: interaction between n-hexane and n-hexane molecules and}$ $\text{ethanol and ethanol molecules is more than the interaction between}$ $\text{hexane and ethanol molecule.}$ $\text{When a solution does not obey Raoult's law over the entire range of}$ $\text{concentration, then it is called a non-ideal solution. The cause for}$ $\text{these deviations lies in the nature of interactions at the molecular}$ $\text{level.}$ $\text{In the case of positive deviation from Raoult's law, A-B interactions}$ $\text{are weaker than those between A-A or B-B, i.e., in this case, the}$ $\text{intermolecular attractive forces between the solute-solvent}$ $\text{molecules are weaker than those between the solute-solute and}$ $\text{solvent-solvent molecules.}$ $\text{The n-hexane and ethanol form a non-ideal solution. The n-hexane is}$ $\text{a nonpolar compound and ethanol is a polar compound. The}$ $\text{interaction between n-hexane and n-hexane molecules and ethanol}$ $\text{and ethanol molecules is more than the interaction between hexane,}$ $\text{and ethanol molecule.}$ $\text{Thus, option second is correct.}$
