Question

State True or False.

The liquid pair of acetone-chloroform shows a positive deviation from Raoult's law.

• A. True
• B. False

Answer 1

The correct option is B False

Due to hydrogen bonding in acetone-chloroform, escaping tendency of both components 'A' and 'B' is lowered showing lower vapour pressure than expected ideally. Hence, such solution will show negative deviation from Raoult's law.

So, option B is correct.
