Detailed explanation-1: -Polar covalent bond is a type of chemical bond where a pair of electrons is unequally shared between two atoms.

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: -Answer and Explanation: The type of bond that has unequal sharing of bonded electrons is a polar covalent bond. In a polar covalent bond one atom is more electronegative than the other. It pulls the electrons closer towards its nucleus and gains a partial negative charge.

Detailed explanation-5: -A polar covalent bond results when electrons are shared equally by the nuclei. One atom can attract more of the electrons than its partner causing the shape of the bond to distort so that one side is bigger than the other and heading towards an ionic bond shape.
