# Question #652d8

$H - C l + {H}_{2} O \to {H}_{3} {O}^{+} + C {l}^{-}$
This solution becomes conductor of electricity due to the presence of ions in it. But pure Hydrogen Chloride in liquid state or in dissolved state in non-polar solvent like $C C {l}_{4}$ is unable to conduct electricity due to lack of formation of ions.
Again glucose(${C}_{6} {H}_{12} {O}_{6}$) ,a covalent compound cannot form ions when dissolved in aqueous or any polar or non-polar medium. So its solution is not a good conductor of electricity.
