Which of the following is not an ideal solution?

Which of the following is not an ideal solution?
  1. Benzene and toluene
  2. Chlorobenzene and 1, 2-dichloro benzene
  3. Methyl iodide and isopropanol
  4. Ethyl bromide and methyl bromide

Solution

An ideal solution obey Raoult’s law at all temperature and pressures. The solute-solute and solvent-solvent interactions are similar to solute-solvent interactions. 1. Benzene + Toluene $ightarrow$ Ideal solution 2. Chlorobenzene $+1,2$-dichlorobenzene $ightarrow$ Ideal solution 3. Methyl iodide + Isopropanol $ightarrow$ Non-ideal solution 4. Ethyl bromide + Methyl bromide $ightarrow$ Ideal solution Hence, only methyl iodide and isopropanol is not an ideal solution.
