n-Octane is non polar and can dissolve non-polar solutes. It cannot dissolve polar (and ionic) solutes. Cyclohexane is non polar.
Hence, easily soluble in n-octane.
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 < CH33CN < Cyclohexane
