Question

which of the following can water not dissolve? nonpolar compounds ionic compounds polar compounds

Explanation:

Water is a polar molecule. By the "like dissolves like" principle, polar (e.g., ionic compounds, polar covalent compounds) substances dissolve in water. Nonpolar compounds (e.g., oil) do not, as their nonpolar nature doesn't interact favorably with water's polarity.

Answer:

A. Nonpolar Compounds
