Which of the following is true about coordination complexes? A)The metal is a Lewis base and the ligands are Lewis acids. B)Only complexes with coordination number six are found in nature. C)When the ligands approach a transition metal ion in an octahedral field,the d_xz,d_yz,and d_xy atomic orbitals are affected the least by the ligands. D)None of the above is true. E)All of the above are true.

Question

In coordination complexes, the metal acts as a Lewis acid (not a base) because it accepts electron pairs from the ligands, which are Lewis bases. Coordination numbers can vary widely, not just six. The statement about the effect of ligands in an octahedral field on d orbitals is correct: the $d_{xz}$, $d_{yz}$, and $d_{xy}$ orbitals are affected the least because they lie between the axes where the ligands approach in an octahedral geometry.
