Detailed explanation-1: -A polar covalent bond is still very strong, but the electron sharing between the atoms is unequal.

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: -Polar covalent bonds result when electrons are unequally shared between atoms, while nonpolar covalent bonds result when electrons are more equally shared between atoms.

Detailed explanation-4: -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.

Detailed explanation-5: -This unequal distribution of electrons is known as a polar covalent bond, characterized by a partial positive charge on one atom and a partial negative charge on the other.
