GENERAL KNOWLEDGE

Detailed explanation-1: -Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared between two atoms. This causes the molecule to develop slight positive and slight negative charges.

Detailed explanation-2: -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-3: -In a polar covalent bond, the electrons are unequally shared by the atoms and spend more time close to one atom than the other. Because of the unequal distribution of electrons between the atoms of different elements, slightly positive (+) and slightly negative (–) charges develop in different parts of the molecule.

Detailed explanation-4: -Covalent bonds form when electrons are shared between atoms and are attracted by the nuclei of both atoms. In pure covalent bonds, the electrons are shared equally. In polar covalent bonds, the electrons are shared unequally, as one atom exerts a stronger force of attraction on the electrons than the other.

Detailed explanation-5: -A covalent bond that has an unequal sharing of electrons, as in part (b) of Figure 4.4. 1, is called a polar covalent bond. A covalent bond that has an equal sharing of electrons (part (a) of Figure 4.4. 1) is called a nonpolar covalent bond.
