Question
Chapter 14, Problem 14D.1ST
Interpretation Introduction
Interpretation:
The value of Z-average molar mass of the sample of poly (vinyl chloride) has to be calculated.
Concept introduction:
The tendency of the particles to stick together is known as intermolecular attraction. A liquid has several measurable properties that depend on intermolecular attractions. A sphere has the smallest surface area possible for a drop of any given volume. This tendency towards a minimum surface is the results of surface tension.

- (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?
