A polar bond is covalent bond in which the electrons are transfer unequally between two molecules.

THANKING YOU.
						

							Polar bond is a type of bond  between two atoms in which electrons are shared unequally .and this bond occurs between two atoms when the electro negativity difference is between 0.4 and 1.7.
						

							A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed. This causes the molecule to have a slight electrical dipole moment where one end is slightly positive and the other is slightly negative.

Polar bonds are the dividing line between pure covalent bonding and pure ionic bonding.
Examples:
Water is a polar bonded molecule.
						

							The bond present between  in which two dissimilar atoms having different electro negativities.in that type of compounds the polar bond is present
						

							A polar bond is covalent bond in which the electrons are transfer unequally between two molecules.
EX:water  is the polar bond.
