4. In transition metal complexes, ligands largely interact with metal center via lone pairs: Monodentate ligands interact with metal via a single lone pair, bidentate ligands interact with two lone pairs, and so on. Which of the following ligands would be an example of a bidentate ligand? O a) chloride (CI-) O b) carbon monoxide (C=0) O c) cyanide (C =N) O d) ethylenediammine(NH2-CH2-CH2-NH2)

Which one of the following is true regarding ligands? An example of a monodentate ligand is NH3 None of these are true statements Ligands are either positively charged or contain an empty electron orbital A chelator can be any type of ligand

Dimethyldithiocarbamate (abbreviated as dmdtc) is an anionic bidentate ligand with a chemical formula (S2CNMe2)- - where Me stands for methyl group (-CH3). In the photo above, this ligand coordinates to a metal through its 2 sulfur atoms (where M represents a metal). When three dmdtc ligands bind to a ferric ion (Fe3+), a stable coordination complex called ferbam is formed. Given this information, answer / identify the following. complex geometry hybridization type of the central atom coordination number

Which of the following is a necessary characteristic of a ligand? (there may be more than one correct answer)    A ligand must be an amine.    A ligand must be high spin.    A ligand must be a Lewis base.    A ligand must be an electron pair donor.    A ligand must be an anion.
