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

Explanation

`a.` Like dissolves like.
Both `n-` octane and cyclohexane are non`-` polar. Hence they are soluble.
`KCl` is an ionic compound whereas `n-` octance is non`-` polar. Hence, `KCl` is insoluble is `n-`octance.
The increasing order of solubility is `:`
