Answer
Liquid hydrogen chloride (HCl) is a covalent compound and does not contain free ions in the liquid state. Therefore, it cannot conduct electricity.
On the other hand, molten sodium chloride (NaCl) contains freely moving Na⁺ and Cl⁻ ions. These ions carry electric charge through the molten salt. Therefore, molten NaCl conducts electricity.
