Arrange the following compounds in increasing order of their solubilities in chloroform: NaCl, CH3OH, cyclohexane, CH3CN

Question

Arrange the following compounds in increasing order of their solubilities in chloroform:

\(NaCl, CH_3OH, \text {cyclohexane}, CH_3CN \)

(1) NaCl < \(CH_3CN < CH_3OH\) < Cyclohexane 

(2) \(CH_3OH < CH_3CN\) < NaCl < Cyclohexane 

(3) NaCl < \(CH_3OH < CH_3CN <\) Cyclohexane 

(4) Cyclohexane \(< CH_3CN < CH_3OH\) < NaCl

Answer 1

Correct option is (1) NaCl < \(CH_3CN < CH_3OH\) < Cyclohexane 

Since \(CHCl_3\) 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.

\(NaCl < CH_3CN < CH_3OH < Cyclohexane\)
