Question

When acetone and chloroform are mixed together, hydrogen bonds are formed between them. Which of the following statements 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 increases
• C. On mixing acetone and chloroform negative deviation is shown since there is decrease 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 decrease in vapour pressure

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

Hence, option C is correct.
