Solution: We can say that the polar bonds are formed between two atoms which have an electronegativity difference like HCl (here Cl is more electronegative than H) and a polar bond is formed between two atoms of the same element like O2, N2
A molecule is polar if there is some dipole moment and non-polar if the overall dipole moment is zero
In the case of CH4, the polar bond is formed between C and H but CH4 is a non-polar molecule because all the dipole moment cancel each other and the net resultant dipole is zero

A covalent bond is a bond in which electrons are shared between atoms of elements
A covalent bond is a
bond in which electrons are shared between atoms of elements. A
covalent bond can be polar or nonpolar. In a nonpolar covalent
bond, the bond is between two identical atoms and the electrons are
evenly shared between the atoms.In contrast, in a
polar covalent bond, the bond is between two nonidentical atoms and
the electrons are unevenly shared between the atoms. The uneven
sharing of electrons takes place because of the difference in the
electronegativity...
