Answer
Hydrogen chloride gas
Reason — Hydrogen chloride is a covalent gas and does not conduct electricity in its pure liquid state because it has no free ions. However, when dissolved in water, it forms hydrochloric acid (H3O+ and Cl- ions), which conducts electricity very well due to the presence of free ions.
