2. Hydrogen chloride is a gas in it’s pure form and does not conduct
electricity.

Reason- It’s a covalent molecule and does not carry charges.

But aqueous HCl (hydrochloric acid) behaves as a good conductor of electricity.

Reason- As HCl is a polar covalent molecule, it dissociates into it’s respective
-

ions (H & Cl ) and conducts electricity.
• Difference between Non polar covalent bonds, polar covalent bonds &
ionic bonds-
