Question

2a. Platinum tetrachloride, [PtCl4], belongs to the point group Dah. Determine how the s, p, and d orbitals of the Pt ion would behave when operated on by all of the D4h symmetry elements. Use the attached D4h character table to assign a symmetry label to each of these orbitals. 2 Cl Pt Cl Orbital 2C2 (z)(x. v) (dihedral) Label Platinum s Platinum px Platinum p Platinum pz Platinum dz2 Platinum dx2-y2 Platinum d Platinum dxz Platinum dyz LGO #1 LGO #2 2 0 0 0 -210|2|0|0 2 0 0 0 2 0 200

Answer 1

when u compare the character table which gives irreducible representation

on comparing p prbitals reducible representation matches with Eg so they belong Eg symmetry

where as reduible representtion corresponding to d orbials which is given in the question matches with Eu symmetry in character table of D 4h point group.
