NH3 replaces H20 ligands

Postby Junwei Sun 4I » Thu Nov 21, 2019 10:42 pm

In class Dr. Lavelle talked about transition metal cations in solution form complex with H20, and when NH3 or K+CN- are added those species will replace the H20 ligands. Why does that happen and how? Thanks!

According to my notes, these species are electron rich, replacing the H20 ligands, which is an easy way to make coordination compounds. I'm not too positively sure if the main reason is that the species are electon rich. There may be other factors to it that he did not discuss in class.
