Based on solute - solvent interactions, arrange the following in order of increasing solubility in n - octane and explain. Cyclohexane, KCl, `CH_(3)OH, CH_(3)CN`.

Explanation

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 as like dissolves in like.
The order of increasing polarity is :
Cyclohexane `lt CH_(3)CN lt CH_(3)OH lt KCl`
Therefore, the order of increasing solubility is :
`KCl lt CH_(3)OH lt CH_(3)CN lt` Cyclohexane.
