A Figure that represents a face-centered tetragonal unit cell as a body-centered tetragonal lattice with a smaller unit cell is to be determined. Concept introduction: The body-centered cubic system has one lattice point at the center of the unit cell with the lattice points at eight corners. Therefore, it has total two lattice points. Face-centered cubic system has lattice points on the six faces of the unit cell in addition with the corner lattice points. Therefore, it has total four lattice points. To determine: A Figure in which a face-centered tetragonal unit cell is redefined as a body-centered tetragonal lattice with a smaller unit cell.

(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).
