1. having no net electrical charge. A nonelectrolyte is a substance which does not ionize in solution. Compare with theoretical yield and actual yield . Compare with covalent compound , ionic compound and polar bond . An asymmetric molecule containing polar bonds .
Alkanes are usually asymmetric but are nonpolar because they contain no polar bonds.
Polar molecules are electric dipoles and they attract each other via dipole-dipole forces . An insoluble substance that has been formed from substances dissolved in a solution. Precipitation is the conversion of a dissolved substance into insoluble form by chemical or physical means. Compare with reactant . A substance that is produced during a chemical change .
