Question

When acetone and chloroform are mixed, hydrogen bonding takes place between them. Such a liquid pair ______.

Options

• causes positive deviation from Raoult’s law

• causes negative deviation from Raoult’s law

• causes no deviation from Raoult’s law

• forms an ideal solution

Answer 1

When acetone and chloroform are mixed, hydrogen bonding takes place between them. Such a liquid pair causes negative deviation from Raoult’s law.

Explanation:

When acetone and chloroform are mixed, hydrogen bonding occurs between them. This increases intermolecular attraction, leading to lower vapour pressure than expected. Hence, the solution shows a negative deviation from Raoult’s law.
