Question

Based on solute-solvent interactions, arrange the following in order of increasing solubility in n-octane and explain. Cyclohexane, KCl, CH₃OH, CH₃CN. 

Answer 1

n-octane is a non-polar solvent. Therefore, the solubility of a non-polar solute is more than that of a polar solute in the n-octane.

 The order of increasing polarity is:

 Cyclohexane < CH₃CN < CH₃OH < KCl Therefore, the order of increasing solubility is: KCl < CH₃OH < CH₃CN < Cyclohexane
