Question

The system that forms maximum boiling azeotrope is:

• A. CS\(_2\) and acetone
• B. Benzene and toluene
• C. Ethanol and acetone
• D. Chloroform and acetone

Hint:

Azeotropes can be minimum or maximum boiling. Maximum boiling azeotropes exhibit strong intermolecular attractions.

Answer 1

The Correct Option is D

A maximum boiling azeotrope occurs when a mixture exhibits strong intermolecular interactions, leading to a lower vapor pressure and a higher boiling point. The chloroform-acetone mixture forms strong hydrogen bonds, preventing easy separation and increasing boiling point.
