Which of the following mixtures does not form an azeotrope at atmospheric pressure ?
Correct answer: A. None of these
- A. None of these
- B. Methyl alcohol-acetone
- C. Butyl acetate-water
- D. Water-alcohol
Explanation
Water-ethanol, methanol-acetone, and butyl acetate-water are known azeotropic systems at atmospheric pressure, with the last commonly forming a heterogeneous azeotrope. Hence none of the listed mixtures is the exception.
