Based on the solute solvent interactions, arrange the following in the order of increasing solubility in n-octane. A. Cyclohexane B. KCl C. CH3OH D. CH3NH2 E. CH3CN Choose the correct answer from the options given below: |
A < B < C < D < E B < C < E < D < A C < B < A < E < D B < C < D < E < A |
B < C < E < D < A |
n-Octane is nonpolar and can dissolve non-polar solutes. It cannot dissolve polar (and ionic) solutes. Cyclohexane is non-polar. Hence, easily soluble in n-octane. Methyl amine is less polar than acetonitrile (CH3CN). Methanol and acetonitrile are polar and have very low solubility in n-octane. KCl is ionic compound and hence, insoluble in n-octane. The increasing order for solubility in n-octane is as follows: KCl < CH3OH < CH3CN < CH3NH2 < Cyclohexane i.e., B < C < E < D < A. |
