The model for bonding in complex ions that considers the metal-ion/ligand bonding as an electrostatic attraction of the metal ion nucleus for ligand electrons,with repulsions between ligand electrons and the electrons of the central metal ion,is called the ________.
A)atomic orbital theory
B)crystal field theory
C)complexation theory
D)molecular orbital theory
E)VSEPR theory

Question

Quizplus · Accepted Answer

The description of the bonding in complex ions provided in the question matches the key concepts of crystal field theory. This theory explains the bonding in complex ions by considering the interaction between the metal ion and its surrounding ligands as electrostatic in nature. It also takes into account the repulsion between the negatively charged electrons in the ligands and the electrons in the d-orbitals of the metal ion. The other options listed in the question (atomic orbital theory, molecular orbital theory, and VSEPR theory) are not directly related to the bonding in complex ions, or are less commonly used in this context. Complexation theory is a more general term that refers to the study of the formation and properties of complexes in chemistry, and does not specifically describe the bonding model.
