Question
Chapter 1, Problem 1B.1DQ
Interpretation Introduction
Interpretation: The critical specifications and analysis of the assumptions that underline the kinetic model of gases have to be stated.
Concept introduction: According to the kinetic theory of gases, there are large numbers of identical particles that are present in gases. These particles are tiny and very far from each other. The volume occupied by the gaseous molecules is almost negligible in comparison of the space that is present between the particles.

- (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?
