Textbook Problem 9C.7

[Andy Nguyen 2K]

Hi,
What are chelating complexes? How do I solve this problem?

[Roma Vashi 3L]

Chelating complexes can be formed from a ligand that forms a ring around the central metal atom. For this question, only B would form a chelating complex because the 2 amine groups can coordinate to the same metal atom. For A & C, the ligands would bind to 2 different metal centers because of their arrangement.
