Question

For the hypothetical molecule (η4 -C4H4)Mo(CO)4: a. Assuming C4v geometry, predict the number of infrared-active C–O bands. b. Sketch the π molecular orbitals of cyclobutadiene. For each, indicate which s, p, and d orbitals of Mo are of suitable

Answer 1

(an) In ferroncene, Fe(C3110, when two clisrings are in obscured adaptation, the gathering orbitals framed by them have a place with Dm point gathering. For each gathering orbital. assess the impact of different symmetry operations display in the Dm point gathering. At that point contrast these outcomes and the irreducible portrayals recorded in the Ds, character table. At that point relegate marks to each gathering orbital. The symmetry marks for the gathering orbitals are given beneath 2 hub

(b) In ferroncene.

At that point contrast these outcomes and the irreducible portrayals recorded in the D 5 character table. At that point allot names to each gathering orbital. The symmetry marks for the nuclear orbitals of Fe particle in Dm condition are given in the accompanying table.
