chelates

[connie ma 3G]

I just watched Wednesday's lecture and am very confused. How do you know/tell if a ligand is going to form a ring of atoms that would make the complex into a chelate?

[Jiapeng Han 1C]

Typically, for a chelate, the ligand must not be a monodentate. This means the ligand must have multiple lone pairs so that it can form two or more coordinate bonds with the central atom.

^exactly. If there are multiple lone pairs available for other compounds to bond to, it is more likely to form a coordinate compound.

I had the same question! Marking this for later.

[LeanneBagood_2F]

so the only thing needed for a chelate is that there needs to be multiple lone pairs? and once something is a chelate we automatically know it'll form a coordinate compound?
