Sigma bond | Pi bond | |
|---|---|---|
Formation | The sigma bond is formed by the head-to-head (or end-to-end) overlap of the hybrid or atomic orbitals. | A pi bond is an additional bond over the sigma bond formed by the side-to-side (or lateral) overlap of the perpendicular p-atomic orbitals. |

|---|---|---|---|
Ionic bonds form due to the complete transfer of electrons. | Covalent bonds form due to sharing of electrons. | Metallic Bond forms between a Metal (cation) and delocalized electrons. |
The strength of polar-nonpolar interactions is affected by the atomic size of the nonpolar atom (or molecule) and the electronegativity of the polar molecule.
Atoms primarily form three types of bonds – ionic, covalent, and metallic.
We start by exploring the Octet Rule that determines Ionic and Covalent bonds.

Prerequisites:
Inorganic chemistry describes oxidation in two ways. The first method is through the loss of electrons, and the second is by the increase in oxidation number.
For an electrode in contact with an electrolyte solution having similar ionic nature, if the tendency of the electrode is to lose electrons and undergo oxidation reaction, the electrode is said to have an oxidation potential. Example, Zn electrode dipped in the ZnSO4 electrolyte solution.
Learning Objective: To learn about chain or nuclear isomerism, a subtype of structural isomerism.
