Question

16, When acetone and chloroform are mixed, hydrogen bond is formed between the O in acetone and the H in chloroform. This will result in a(maximum or minimum) boiling azeotrope.

Explanation / Answer

16. The ebullition point of chloroform is 61.2°C and the acetone is 56.5°C but the ebullition point of their azeotrope is 64.43°C . So, it is a maximum boiling azeotrope because the ebullition point of the azeotrope is higher than the ebullition point of pure components.
