Which from the following liquid mixtures behaves nearly an ideal solution?
Options
- ABenzene + toluene
- BPhenol + aniline
- CChloroform + acetone
- DEthanol + acetone
Correct answer
A. Benzene + toluene
Step-by-step solution
An ideal solution requires that the intermolecular forces between components (A–B) match those within pure components (A–A and B–B), leading to no enthalpy or volume change on mixing and adherence to Raoult's law across all concentrations. Benzene + toluene : Both are nonpolar hydrocarbons with similar molecular structures and sizes, exhibiting comparable London dispersion forces. This results in nearly ideal behavior. Phenol + aniline : Hydrogen bonding between phenol ( C₆ H₅OH ) and aniline ( C₆ H₅NH₂ ) exceeds t
