C. pure acetone

3. Do chloroform and acetone form an ideal solution?

A. no

B. cannot be determined from the information given

C. yes

4. If a chloroform-acetone mixture with an acetone mole fraction of 0.6 is subjected to fractional distillation, what is the composition of the distillate?

A. pure azeotrope

B. pure acetone

C. none of the choices shown

D. pure chloroform

5. The acetone-chloroform intermolecular attractions are _________________ the acetone-acetone or chloroform-chloroform attractions.

A. less than

B. equal to

C. greater than

6. Mixtures of chloroform and acetone exhibit ________________deviations from Raoult’s Law.

A. no

B. positive

C. negative

7. Which is more volatile?

A. chloroform

B. Not enough information given to make a determination.

C. acetone

Answer 1

Answer 1

Option A is correct

Raoults law

Answer 2

Option A is correct

As mole fraction of Chloroform is more than acetone so more number of vapours pf chloroform will form and will be collected as distillate.
