The mixture that forms maximum boiling azeotrope is:
Water + Nitric Acid
Ethanol + Water
Acetone + Carbon disulphide
Heptane + Octane
The Solutions that show large negative deviation from Raoult's law from maximum boiling azeotrope at a specific combination.
Nitric acid and water is the example of this class of azeotrope.
68% Nitric acid + 32% by mass with a boiling point of 393.5 K.
Water + Nitric Acid
Option 2)Ethanol + Water
Option 3)Acetone + Carbon disulphide
Option 4)Heptane + Octane
