- how to determine irreducible representations of pyrazine? point group d2hWhat is the reducible representation for BH4+The molecule PtCl 2 - is an important square planar starting material in synthetic inorganic chemistry. Using the p orbitals of Cl as the basis find the irreducible representations of the p orbitals and indicate which orbitals could possibly overlap with any of the orbitals on Pt . Assume that the pz orbitals on Cl are orientated in the same direction as the principle rotation axis, px orbitals are pointed at the Pt , and the py orbitals are orthogonal to the px orbitals. Show the characters of each orbital and identify which orbitals on Pt would match from a pure symmetry standpoint.
- Explain what is meant by irreducible representations, non-degenerate representations and degenerate representations. Which point groups will have degenerate directional properties?What do you expect the structure of Ge2H4 to look like ? sketch the structure in a clear three dimensional representation and give it's point group.- Determine the irreducible representations with reasons in the following character table. C I R R, R xy.
