Sugar is made up of clear, colorless crystals that dissolve easily in water, but the crystals and their solution do not conduct electricity. Which statement describes sugar?

Sugar dissolves in water but neither its crystals nor its solution conduct electricity, so it does not contain mobile charged particles such as ions. Sugar is a molecular substance whose atoms are held together by covalent bonds. Therefore, the correct choice is “It is made up of atoms that are held together by covalent bonds.”
