The Fuoss-Eigen reaction and the Eigen-Wilkins mechanism describe substitution reactions involving these compounds. Those substitution reactions involving these compounds generally come in associative, dissociative, or interchange mechanisms. In the trans effect, when these compounds are oriented trans to each other, the rate of their substitution increases. In the nephelauxetic effect, these compounds decrease the (*) B Racah parameter. These compounds name a field theory that combines molecular orbital theory and crystal field theory. When bonded to more than one atom, these compounds are called polydentate and act as chelators. Eta notation is used to describe the

These compounds name a field theory that combines molecular orbital theory and crystal field theory. When bonded to more than one atom, these compounds are called polydentate and act as chelators. Eta notation is used to describe the hapticity of these molecules. For 10 points, name these molecules that bind to central metals in coordination complexes.
