# What is a polar covalent bond?

Feb 13, 2015

A covalent bond whose shared pair of electrons tend to lie closer to one of the two atoms forming the bond is called a polar covalent bond .

The atom which tends to attract these shared electrons, or more precisely speaking, the electron density of the bond towards itself is said to be electronegative .

For example, the bond between H and F in an HF molecule is a polar covalent bond. The F atom being more electronegative tends to attract the shared electrons towards itself.

This exaggerated animation should help in understanding what goes on between the two atoms :) :
