What are polar bond?

Polar bonds are ionic bonds that involve complete electron transfer.
Polar bonds have no dipole moment due to equal electronegativity.
Polar bonds are covalent bonds between atoms with different electronegativities, resulting in a dipole moment.
Polar bonds are formed between identical atoms only.

What are nonpolar bonds?

Nonpolar bonds are ionic bonds where electrons are transferred between atoms.
Nonpolar bonds occur only in metallic compounds with free electrons.
Nonpolar bonds are formed when atoms have a large difference in electronegativity.
Nonpolar bonds are covalent bonds where electrons are shared equally between atoms.
