Question

Choose the ideal solution from the following:

• A. Carbon disulphide and acetone
• B. Phenol and Aniline
• C. Chloroform and Acetone
• D. Ethyl iodide and ethyl bromide

Answer 1

Answer:

D. Ethyl iodide and ethyl bromide

• Ideal Solutions are those that obey Raoult's law over the entire range of concentration and temperature, with $\Delta H_{\text{mixing}} = 0$ and $\Delta V_{\text{mixing}} = 0$.

• This typically happens when the components have very similar structures, sizes, and intermolecular forces (such as mixtures of similar halogen derivatives like ethyl iodide and ethyl bromide).
