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

Answer :

Now n-octane is non-polar solvent due to long chain saturated structure. We know that “like dissolves like” so a non-polar compound will be more soluble in non-polar solvent as compared to polar compound.

So cyclohexane is non-polar due to symmetric structure. KCl is ionic in nature as it will dissociate into K + and Cl- ions. CH3CN is polar as mentioned above and CH3OH is also polar in nature.

The order of increasing polarity is:

Cyclohexane < CH3CN < CH3OH < KCl (O is more electronegative than N)

Therefore, the order of increasing solubility is:

KCl < CH3OH < CH3CN < Cyclohexane
