Question

Give a suitable example, describe the formation of

polar covalent bonds

Answer 1

1. A covalent bond is formed due to the sharing of electrons between two atoms.
2. A polar covalent bond is a covalent bond in which the atoms that share electrons have differences in their electronegativities.
3. In a polar covalent bond, the shared pair of electrons lie more toward the more electronegative atom between the two.
4. For example, The formation of $\mathbf{H}\mathbf{-}\mathbf{Cl}$ bond is a polar covalent bond. Here, Chlorine is more electronegative than Hydrogen. So, the shared pair of electrons lie more towards $\mathbf{Cl}$atom.
