Though we haven’t looked at anything but a few particular MO diagrams, you can extrapolate what you have learned to other diagrams which include d orbitals. Use the diagram shown below, and what you know from doing MO diagrams of 2nd row diatomics to answer the following questions.    Is the ion shown paramagnetic or diamagnetic? [ Select ] diamagentic paramagnetic What is the name of the orbital labelled A? [ Select ] sigma 4p pi 4d sigma 4d* pi 4d* sigma 4s pi 4p sigma 4d sigma4s* sigma 4p* What is the bond order?  [ Select ] 3.5 5.5 2 4.5 6 1.5 4 3 2.5 5
