Distinguish between a sigma and a pi bond.
The following are the differences between sigma and pi-bonds:
| Sigma $(\sigma)$ Bond | Pi $(\pi)$ Bond |
| $(a)$ It is formed by the end-to-end overlap of orbitals. | $(a)$ It is formed by the lateral overlap of orbitals. |
| $(b)$ The orbitals involved in the overlapping are $s-s, s-p,$ or $p-p$. | $(b)$ These bonds are formed by the overlap of $p-p$ orbitals only. |
| $(c)$ It is a strong bond. | $(c)$ It is a weak bond. |
| $(d)$ The electron cloud is symmetrical about the line joining the two nuclei. | $(d)$ The electron cloud is not symmetrical about the internuclear axis. |
| $(e)$ It consists of one electron cloud,which is symmetrical about the internuclear axis. | $(e)$ There are two electron clouds lying above and below the plane of the atomic nuclei. |
| $(f)$ Free rotation about $\sigma$ bonds is possible. | $(f)$ Rotation is restricted in case of $\pi$ bonds. |
