Arrange the following compounds in increasing order of their solubilities in chloroform: $\mathrm{NaCl}, \mathrm{CH}_3 \mathrm{OH}$, cyclohexane, $\mathrm{CH}_3 \mathrm{CN}$
  1. $\mathrm{NaCl} \lt \mathrm{CH}_3 \mathrm{CN} \lt \mathrm{CH}_3 \mathrm{OH} \lt $ Cyclohexane
  2. $\mathrm{CH}_3 \mathrm{OH} \lt \mathrm{CH}_3 \mathrm{CN} \lt \mathrm{NaCl} \lt $ Cyclohexane
  3. $\mathrm{NaCl} \lt \mathrm{CH}_3 \mathrm{OH} \lt \mathrm{CH}_3 \mathrm{CN} \lt $ Cyclohexane
  4. Cyclohexane $ \lt \mathrm{CH}_3 \mathrm{CN} \lt \mathrm{CH}_3 \mathrm{OH} \lt \mathrm{NaCl}$

Solution

Since $\mathrm{CHCl}_3$ is an organic solvent so, covalent (non-polar) compounds will be more soluble in it. As the dipole moment of solute increases, solubility in chloroform decreases. Hence increasing order of solubility. $\mathrm{NaCl} \lt \mathrm{CH}_3 \mathrm{CN} \lt \mathrm{CH}_3 \mathrm{OH} \lt $ Cyclohexane
