What is a hybrid orbtial?
Hybrid orbitals are types of atomic orbital that result when two or more atomic orbitals of an isolated atom mix such as the number of hybrid orbital on a covalently bonded atom are equal to the number of atomic orbitals used to form the hybrid orbitals.
Hybrid orbitals are usually involved in sigma bonds in polyatomic molecules; pi bonds usually involve the overlap of hybridised orbitals.
. For example, if one s –and p – orbitals intermix and redistribute their energies, two equivalent sp orbitals are formed called hybrid orbitals.
