When a compound can't be solvated to any significant extent is called what?

When a compound can't be solvated to any significant extent, it is referred to as being "insoluble." Insoluble compounds do not dissolve appreciably in a given solvent, leading to the formation of a precipitate or remaining undissolved in the solution. This lack of solubility is often due to strong intermolecular forces within the compound that outweigh the interactions with the solvent molecules.
