Unequal sharing of electron pair results in:

B. Polar covalent bond

• Ionic bonds involve a complete transfer of electrons from one atom to another.
• Hydrogen bonds are a specific type of dipole-dipole attraction between a hydrogen atom bonded to a highly electronegative atom (O, N, F) and another electronegative atom.
• Polar covalent bonds arise due to the unequal sharing of electrons between atoms with different electronegativities.
