The boiling point of an azeotropic mixture of water and ethanol is less than that of water and ethanol individually. The mixture shows:

1. No deviation from Raoult's law

2. Positive deviation from Raoult's law

3. Negative deviation from Raoult's law

4. That the solution is unsaturated

The azeotropic mixture of water and ethanol boils at 78.15 ^oC. When this mixture is distilled, it is possible to obtain-

1. Pure H₂O

2. Pure C₂H₅OH

3. Pure H₂O as well as pure C₂HOH

4. Neither H₂O nor C₂H₅OH in their pure state 

The type of inter-molecular interactions present in:

The mixture among the following that forms maximum boiling azeotrope is:
