what is polar covalant bond
Answers
polar covalent bond exists when atoms with different electronegativities share electrons in a covalent bond. ... The unequal sharing of the bonding pair results in a partial negative charge on the chlorine atom and a partial positive charge on the hydrogen atom.

Answer:
°•°In general, a polar bond is a certain class of a covalent bond. We can also say that it is the dividing line between the formation of a pure covalent bond and an ionic bond. However, if we want to define it more accurately, a polar covalent bond is a bond that exists between two atoms consisting of electrons that are unevenly distributed. Due to this state, the molecules tend to have some electrical dipole moment wherein the two ends are either slightly positive or negative.
•°• Electronegativity plays a major role in determining the different types of covalent bonding. Electronegativity is the tendency of an atom to attract a shared pair of an electron towards itself. It has no units simple it is a tendency. The covalent bond formed between two atoms in molecules whose electronegative difference exists is known as a polar covalent bond.
