According to valence bond theory, what would be the set of hybrid orbitals used when a Period 4 transition metal forms a square planar complex? A)d ² sp B)d ² p ² C)dsp ³ D)sp ³ E)dsp ²

Question

Quizplus · Accepted Answer

According to valence bond theory, in a square planar complex, the central metal atom uses 4 hybrid orbitals to bond with the 4 ligands. These hybrid orbitals are made up of a combination of d, s and p orbitals. The notation for these hybrid orbitals is dsp2, which means there are two d orbitals, one s orbital, and three p orbitals involved. Therefore, the best choice is E, which is dsp ².
