TYPES OF HYBRID ORBITAL

There are two types of hybrid orbitals:
(1)Sigma hybrid orbital 
(2)Pi hybrid orbital

σ(SIGMA) HYBRID ORBITAL:
It is a hybrid orbital having cylinderical symmetry in relation to the line joining the nuclei which are linked.For sigma hybrid orbital λ=0.We measure the bond angle for a given atom by considering the bond angle beteen its sigma bond.



ㄫ(PI)HYBRID ORBITAL:
It is a type of hybrid orbital for which  λ=1.The axes of a π bond and a σ  bond always coincide with each other.
