Answer
A solution of hydrogen chloride in water gives ions,
HCl + H2O ⟶ H3O+ + Cl-
These ions are responsible for conducting electricity and turning blue litmus red. Due to the presence of hydronium [H3O+] ions, aqueous solution of HCl is an electrolyte.
Toluene is an organic solvent and HCl is a covalent compound. A solution of HCl in toluene contains only molecules and not ions due to which it does not conduct electricity. The absence of hydronium [H3O+] ions make the solution neutral and does not act as an electrolyte.
