Solution

Hydrogen chloride (HCI): The strong nuclear charge of chlorine atom (the electronegativity of chlorine 3) attracts the shared electron pair towards itself, i.e., the negative charge shifts towards the chlorine atom thereby developing a slight negative charge on it.
The hydrogen atom (electronegativity 2.1) develops a slightly positive charge.
Therefore, a polar covalent bond is formed.
