- (8 pts, Please show all work) An electron is excited from the
highest occupied molecular orbital of N2 to the lowest
unoccupied molecular orbital of N2.
- Specify the orbitals involved in this transition: From ______ To______
- Does this excitation make the bond order higher, lower, or have no change?
- Does this excitation make the bond length longer, shorter, or have no change?
- Does this excitation make the bond stronger, weaker, or no change?
Homework Answers
For N2,
Electronic configuration is given below in MO diagram.
Transition takes place from HOMO to LUMO.
So transition takes place from 
to
*
Since electron is transferred to
* ,an ati bonding orbital, the molecule is slightly destabilized.
Therefore,
Bond order decreases
Bond length increases
Bond weakens.

Electron transport chains (ETCs), large proteins through which electrons move, play important roles in two of nature's fundamental processes: (1) the conversion of electromagnetic energy from the Sun into the energy in the chemical bonds in glucose molecules and (2) the conversion of the energy in these glucose molecules into useful forms for metabolic processes, such as muscle contraction, building proteins, and respiration. Respiratory ETCs are located in the inner membranes of mitochondria, the power plants of eukaryotic cells. ETCs...
