Ligands

Postby Natallie K 3B » Sun Nov 29, 2020 7:32 pm

Are all ligands Lewis bases? Are all Lewis bases ligands? What is the relationship between the two?

Yes, I believe that all Lewis bases are ligands and vise versa because both definitions define a compound that can give away two electrons to form a coordinate bond.

All ligands are Lewis bases but not all Lewis bases are ligands

So if all ligands are Lewis bases, does that mean all transitional metals are cations? Or can Lewis base ligands only bond with cation transitional metals?

All transition metals form cations so ligands are Lewis bases that donate an electron pair to a TM cation.

Hope this helps!

I am pretty sure that most, if not all, of the transition metals create cations, which means that all ligands must be lewis bases to provide electron pairs for bond formation.
