Question

Why is HCl considered as a polar covalent compound?

Answer 1

Chlorine is significantly more electronegative than hydrogen. It strongly pulls the shared pair of electrons towards itself, developing a partial negative charge (δ⁻) on the chlorine atom and a partial positive charge (δ⁺) on the hydrogen atom, resulting in a polar covalent bond (H^δ+ - Cl^δ−).
