Arrange the following compounds in increasing order of their solubilities in chloroform: NaCl,CH3OH\mathrm{NaCl}, \mathrm{CH}_3 \mathrm{OH}, cyclohexane, CH3CN\mathrm{CH}_3 \mathrm{CN}

Options

  1. ANaCl<CH3CN<CH3OH<\mathrm{NaCl} \lt \mathrm{CH}_3 \mathrm{CN} \lt \mathrm{CH}_3 \mathrm{OH} \lt Cyclohexane
  2. BCH3OH<CH3CN<NaCl<\mathrm{CH}_3 \mathrm{OH} \lt \mathrm{CH}_3 \mathrm{CN} \lt \mathrm{NaCl} \lt Cyclohexane
  3. CNaCl<CH3OH<CH3CN<\mathrm{NaCl} \lt \mathrm{CH}_3 \mathrm{OH} \lt \mathrm{CH}_3 \mathrm{CN} \lt Cyclohexane
  4. DCyclohexane <CH3CN<CH3OH<NaCl\lt \mathrm{CH}_3 \mathrm{CN} \lt \mathrm{CH}_3 \mathrm{OH} \lt \mathrm{NaCl}

Correct answer

A. NaCl<CH3CN<CH3OH<\mathrm{NaCl} \lt \mathrm{CH}_3 \mathrm{CN} \lt \mathrm{CH}_3 \mathrm{OH} \lt Cyclohexane

Step-by-step solution

Since CHCl3\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. NaCl<CH3CN<CH3OH<\mathrm{NaCl} \lt \mathrm{CH}_3 \mathrm{CN} \lt \mathrm{CH}_3 \mathrm{OH} \lt Cyclohexane
