What is polydentate and what's its significance within this course and chemistry in general?

Polydentate refers to ligands that have multiple donor atoms and therefore can bind to a metal at multiple sites. Its significance can be seen in its biological aspects such as heme complexes and other things like that.

Polydentate is when a ligand can have multiple bonding sites to the transition metal. An example of this would be ethylenediamine (en) or diethylenetriamine (dien). Polydentates form chelates where the ligand forms a ring of atoms including the transition metal cations. These cations are bound tightly together.

is this going to be a big part of the test do you think? do you know of any good sources to help learn this.

Polydentate describes how many bonding sites a ligand can have to a transition metal.
