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)

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.
