Detailed explanation-1: -In a polar covalent compound, electron pair/pairs between participating atoms are equally shared, whereas, in a non-polar covalent compound, electron pair/pairs between participating atoms are not equally shared.
Detailed explanation-2: -A nonpolar covalent bond is a covalent bond in which the bonding electrons are shared equally between the two atoms. In a nonpolar covalent bond, the distribution of electrical charge is balanced between the two atoms.
Detailed explanation-3: -A covalent bond that has an equal sharing of electrons (part (a) of Figure 4.4. 1) is called a nonpolar covalent bond.
Detailed explanation-4: -The bonding electrons in polar covalent bonds are not shared equally, and a bond moment results. However, a molecule may be polar or nonpolar depending on its geometry.
Detailed explanation-5: -Nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal. The result is a bond where the electron pair is displaced toward the more electronegative atom.
