Polar Covalent Bonds

Polar Covalent Bond

A polar covalent bond is a bond formed when the shared pair of electrons in a covalent bond are not

shared equally.

This is due to different elements having different electronegativities.

CONT.

• Polar bonds happen when ever atoms with large electro-negativity differences connect. The electrons are not shared evenly, they get taken by the anion.

EG: BONDING BETWEEN HYDROGEN AND CHLORINE

REASON

• THE BONDING ELECTRON PAIR WILL BE ATTRACTED MORE TOWARDS ELECTRONEGATIVE CHLORINE ATOM, BECAUSE ELECTRONEGATIVITY OF CHLORINE IS MORE THAN THAT OF HYDROGEN.
