a) prepare a MO energy-level diagram for NO, showing clearly how the atomic orbitals interact to form MOs.
b) how does your diagram illustrate the difference in electronegativity between N and O?
c) predict the bond order and the number of unpaired electrons.
d) NO+ andNO- are also known. compare the bond order of these ions with bond order of NO. which of the three woud you predict to have the shortest bond?why?
