The mixture that forms maximum boiling azeotrope is

The mixture that forms maximum boiling azeotrope is
  1. Water and Nitric Acid
  2. Ethanol and Water
  3. Acetone and Carbon disulphide
  4. Heptane and Octane

Solution

The solutions that show large negative deviation from Raoult’s law form maximum boiling azeotrope at a specific composition. Nitric acid and water is an example of this class of azeotrope. This azeotrope has the approximate composition, 68% nitric acid and 32% water by mass, with a boiling point of 393.5K.
