Answer to Question #203919 in Inorganic Chemistry for Pelin

Question

1.    Which of the following ligands could form chelates? Indicate also the donor atom for each ligand.

 Cl^-,         OH^-,          CN^-,         NO₂^-,        C₂O₄^2- ,    H₂NCH₂CH₂NH₂ ,       H₂NCH₂CH₂CH₃

 

 

Answer 1

H₂NCH₂CH₂NH₂

It coordinates through two N atoms. The remaining ligands are non-chelating. They coordinate through only one atom. Nitro group is ambidentate ligand and coordinates either through N or O but not both.
