For the paddlewheel complex $[$Mo$2($OAc$)4]$:

a$.$ Construct an MO diagram below showing only the d orbital interactions in the metal$-$

metal bond. Label each atomic orbital $($dxy $,$ dxz etc.$),$ and label the orbital interactions

$($sigma$,$ pi$,$ or delta$).$ Make sure to draw the orbitals involved in those interactions $($and

how they line up to form the bonds$)$ and to populate the orbitals with the correct number

of electrons. Note that the z axis is aligned with the Mo$-$Mo bond.

b$.$ Based on the diagram above, calculate the bond order for the Mo$-$Mo bond. Show your

work
