Detailed explanation-1: -A polar covalent bond is a covalent bond in which the atoms have an unequal attraction for electrons and so the sharing is unequal. In a polar covalent bond, sometimes simply called a polar bond, the distribution of electrons around the molecule is no longer symmetrical.
Detailed explanation-2: -A non-polar covalent bond is a type of chemical bond that is formed when electrons are shared equally between two atoms. Thus, in an atom, the number of electrons shared by the adjacent atoms will be the same. The covalent bond is also termed as nonpolar because the difference in electronegativity is mostly negligible.
Detailed explanation-3: -Different atoms have different electronegativities based on how many valence electrons they already have. Atoms of different electronegativities attract electrons unequally. This causes the unequal sharing of electrons, which causes polarity in bonds.
