Which of the following binary mixture does not show the behaviour of minimum boiling azeotropes?
- a
- b✓
- c
- d
Strategy:\n> Minimum boiling azeotropes occur when a system shows large positive deviation from Raoult's Law (weak A-B interactions). Maximum boiling azeotropes occur when there is negative deviation (strong A-B interactions).\n\nAnalysis:\n- (a) (Water + MEK): Positive deviation Min boiling.\n- (c) : Positive deviation Min boiling.\n- (d) : Positive deviation Min boiling.\n- (b) (Phenol + Aniline): These form a strong intermolecular hydrogen bond. This leads to negative deviation and thus a Maximum boiling azeotrope.\n\n
