(a) Interpretation: The element experiencing oxidation or reduction, the species being oxidized or reduced and the change in oxidation number are to be stated. Concept introduction: A species gain or loses electrons to form anions or cations respectively. If an atom loses an electron, the atom is said to be oxidized and the process is called oxidation. Similarly, if the atom gains electrons it is said to be reduced and the process is called reduction. To keep a track on the loss or gain of an electron, a number is assigned in the form of oxidation number.

(15 pts) Consider the molecule B2H6. Generate a molecular orbital diagram but this time using a different approach that draws on your knowledge and ability to put concepts together. First use VSEPR or some other method to make sure you know the ground state structure of the molecule. Next, generate an MO diagram for BH2. Sketch the highest occupied and lowest unoccupied MOs of the BH2 fragment. These are called frontier orbitals. Now use these frontier orbitals as your basis set for producing LGO's for B2H6. Since the BH2 frontier orbitals become the LGOS, you will have to think about what is in the middle of the molecule and treat its basis as well. Do you arrive at the same qualitative MO diagram as is discussed in the book? Sketch the new highest occupied and lowest unoccupied MOs for the molecule (B2H6).
