Question

When acetone and chloroform are mixed together, hydrogen bonds are formed between them, which of the following statement is correct about the solution made by mixing acetone and chloroform

• A. On mixing acetone and chloroform will form an ideal solution
• B. On mixing acetone and chloroform positive deviation is shown since the vapour pressure increase
• C. On mixing acetone and chloroform negative deviation is shown since there is decreases in vapour pressure
• D. At a specific composition acetone and chloroform will form minimum boiling azeotrope.

Answer 1

Answer: (C)

On mixing acetone and chloroform negative deviation is shown since there is decreases in vapour pressure

Answer 2

When acetone and chloroform are mixed together, hydrogen bonds are formed between them which increase intermolecular interactions hence deceases the vapour pressure showing negative deviation.
