Question

Which of the following is a non-ideal solution?

• A. n-hexane and n-heptane
• B. Bromoethane and Chloroethane
• C. Acetone and $CHC{l}_3$
• D. All of the above.

Answer 1

The correct option is C Acetone and $CHC{l}_3$

(a) n-hexane and n-heptane
(b) Bromoethane and Chloroethane
Both are ideal solutions.


An ideal solution obeys Raoult's law at all temperatures and pressures.
The solute-solute and solvent-solvent interactions are almost similar to solute-solvent interactions. No association or dissociation takes place. It does not form an azeotrope mixture.

For (c): acetone and $CHC{l}_3$ are the non-ideal solution and shows negative deviation from Raoult's law
