Which of the following substances is a non-electrolyte?
Answer Details
A non-electrolyte is a substance that does not conduct electricity when dissolved in water. It is usually a covalent compound that does not dissociate into ions when dissolved in water. Among the given substances, only C6H12O6 (glucose) is a non-electrolyte because it is a covalent compound made up of molecules that do not dissociate into ions in water. The other substances are electrolytes because they either ionize or dissociate into ions in water and conduct electricity. H2SO4 and NH4Cl are strong electrolytes because they dissociate completely into ions in water, while CH3COOH is a weak electrolyte because it only partially ionizes in water.
