The system that forms minimum boiling azeotrope is :
Options
- AEthyl alcohol - Water
- BAcetone-Chloroform
- CNitric Acid - Water
- DPhenol-Aniline
Correct answer
A. Ethyl alcohol - Water
Step-by-step solution
Azeotropes are constant boiling mixtures that distill without change in composition. They are classified into two types based on their deviation from Raoult's Law. Minimum boiling azeotropes are formed by solutions showing large positive deviations from Raoult's Law. In such cases, the vapor pressure of the solution is higher than the vapor pressure of the individual components, leading to a boiling point lower than that of either component. Ethyl alcohol and water form a mixture that exhibits a large positive devi
