Question

Distinguish between a sigma and a pi bond.

✓

Answer

Sr. No.	Pi bond	Sigma bond
1	Pi bond is formed by lateral overlapping of orbitals.	Sigma bond is formed by end to end overlapping of orbitals.
2	It is comparatively weak bond.	It is comparatively strong bond.
3	There is only one overlapping orbital is p-p.	The overlapping orbitals are s-s, s-p, p-p.
4	Rotation around pi- bond is restricted.	Rotation is possible around sigma bond.
5	Electron cloud is not symmetrical about the line joining 2 nuclei.	Electron cloud is symmetrical about the line joining 2 nuclei.
6	It is having 2 electron clouds one above the plane of atomic nuclei and one below the plane of atomic nuclei.	It is having 1 electron cloud and that is symmetrical about the inter-nuclear axis.
