what is sigma bond and pie bond ?

Sigma bonds -- Overlapping of two orbitals linearly (by the end-to-end overlap of atomic orbitals) between the two nuclear centres is called sigma bond denoted by the symbol σ. All single bonds are sigma bonds. Sigma bonds are strongest covalent chemical bonds.


pi bonds –  The side-to-side overlap of atomic orbitals along a plane perpendicular to a line connecting the nuclei of the atoms is called pi bond and denoted by the

symbol π. A pi bond can only form after a sigma bond has already formed. It is always part of a double or triple bond.
