Which of the following solutions will follow Raoult's law most closely ?
Correct answer: C. A solution of benzene, toluene and o-xylene
- A. 35% solution of NH3 in water
- B. 35% solution of camphor in water
- C. A solution of benzene, toluene and o-xylene
- D. A solution of polar organic compounds (not of homologue of a series)
Explanation
Benzene, toluene, and o-xylene are similar, nonpolar members of a homologous aromatic series, so their intermolecular interactions are similar and the solution is close to ideal. The polar or strongly interacting water solutions show larger deviations from Raoult's law.
