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: -Coordinate covalent bonds involve the unequal sharing of an electron pair by two atoms, with both electrons (originally) coming from the same atom.

Detailed explanation-3: -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-4: -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.

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.
