Question

are delocalized electron pairs counted in hybrid orbital?

Answer 1

No, delocalized electron pairs, also known as pi (π) electrons, are not included in the hybrid orbital count. Hybrid orbitals are formed by the combination of atomic orbitals and are involved in sigma (σ) bonding. Pi (π) bonding, which involves the overlap of p orbitals, is not considered in the formation of hybrid orbitals.
