3a) The nitrosyl ion, NO*, is a very rare case of a cationic ligand that can function as a Lewis base. Drawthe Lewis structure of this ligand under consideration of the VSEPR rules and indicate any formalcharges on the constituent atoms.3b) How many electrons does the NO* ligand contribute on the ionic model and the neutral model,respectively? Assume that the Metal-N-O bonding angle is 180° upon coordination.

Denticity Denticity is the number of atoms in a ligand that bind to a central atom in a coordination complex. H H For example, ethylene diamine (shown on the right) has two nitrogen atoms with lone pairs that can both bind to a metal. This ligand is bidentate. N: Identify the number of atoms in each ligand that can donate a lone pair. N: O monodentate O not a ligand O bidentate O bidentate O not a ligand O monodentate CH3 O bidentate O not a ligand O monodentate OH O bidentate O monodentate O not a ligand

Select the correct answer below: A) The compound K4[Fe(CN)6] absorbs higher energy light. B) H2O produces a stronger ligand field than CN−. C) The compound K4[Fe(CN)6] is likely a low-spin complex because it contains strong-field ligands. D) The compound [Fe(H2O)6]SO2 is likely a high-spin complex because it contains weak-field ligands.
The cyanide anion CNis a very good ligand towards metal ions.Represent the Lewis formula of the cyanide ion, and by which atom does the cyanide anion coordinates to a metal ion?
Transition metal complexes are highly likely to be colored because of a) the size of the energy gap within the d orbitals and the number of electrons. In ruby, the red color of ruby is attributed to a small amount of Cr³* substituting into Al2O3 which is made up of shared AIO, octahedra. Provide a hypothesis for the origin of the red color observed in ruby. Red pigments tend to be rare. If you had to design a new material that b) had an approximate bandgap that would absorb green, what ideas do you need to employ to find a new semiconductor that does not contain Cd, Hg or Pb as one of the components (see last lecture for ideas).
