Verified Answer
What is polar bond?Chemistry doubt.
Polar Bond Definition
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. The charge of the electric dipoles is less than a full unit charge, so they are considered partial charges and denoted by delta plus (δ+) and delta minus (δ-). Because positive and negative charges are separated in the bond, molecules with polar covalent bonds interact with dipoles in other molecules. This produces dipole-dipole intermolecular forces between the molecules.
Polar bonds are the dividing line between pure covalent bonding and pure ionic bonding. Pure covalent bonds (nonpolar covalent bonds) share electron pairs equally between atoms. Technically, nonpolar bonding only occurs when the atoms are identical to each other (e.g., H2 gas), but chemists consider any bond between atoms with a difference in electronegativity less than 0.4 to be a nonpolar covalent bond.
Carbon dioxide (CO2) and methane (CH4) are nonpolar molecules.
