NAME____ ANSWERS _ The hybridization of one s-orbital, three p-orbitals and two d-orbitals, leads to six d2sp3 hybrid
orbitals. Of the five (5) d-orbitals available, i.e., the dxy, dx2-y2, dxz, dyz and dz2 orbitals,
which two need to be used in d2sp3 hybrid orbital formation? 2+
NH3 2+ N 6.(10) N Co NH3 N Cl NH N OH 2
Answer = __ dx2-yCo
