ideal solutions

Question

Which of the following pairs forms an ideal solution?

RankGuru · Accepted Answer

**Ideal Solutions** follow Raoult's law over the entire range of concentrations.
- Characteristics: $\Delta H_{mix} = 0$ and $\Delta V_{mix} = 0$.
- **Benzene and Toluene** form a nearly ideal solution because they have similar molecular structures, sizes, and nearly identical intermolecular forces ($A-B$ interactions are similar to $A-A$ and $B-B$).
- Other pairs like Acetone-Chloroform show **negative deviation** (due to H-bonding between components), while Ethanol-Water shows **positive deviation**.
