In the valence bond theory, hybridisation of orbitals is an integral part of bond formation.Hybridisation consists of mixing or linear combination of the "pure" atomic orbitals in such a way as to form new hybrid orbitals such as sp, sp^2, sp^3, sp^3d , sp^3d^2 etc. Now answer the following questions : Which of the following atomic orbitals does not participitate in trigonal bipyramidal hybridisation i.e. sp^3d hybridisation ?
