A student attempts to purify a mixture of aniline and nitrobenzene by steam distillation. Which compound will distill over first, and why?
Nitrobenzene, due to its higher molecular weight
Aniline, due to its lower boiling point and formation of less extensive hydrogen bonds with water compared to nitrobenzene
Both will distill over simultaneously as they form an azeotropic mixture
Nitrobenzene, because it is less volatile than aniline
