Chapter 21.4, Problem 23R

To determine

The way one solute can dissolve in both polar and nonpolar solvents.

Explanation of Solution

A good example to explain this is ethanol.

$CH-CH-OH$

The left side of the molecule has non polar characteristics because of $C-C$ and $C-H$ bond which allow to dissolve in non-polar(gasoline).

Right hand side is polar characteristic which allows the molecules to be dissolved in a polar solvent.

Conclusion:

Polar solute can be easily dissolved in polar solvent. Non polar solute can be dissolved in non polar solvent.
