Question
Chapter 5, Problem 5B.5DQ
Interpretation Introduction
Interpretation: The reason for the fact that the freezing point constant are typically larger than the corresponding boiling point constants of a solvent has to be stated.
Concept introduction: The properties which depend on the ratio of the number of solute molecules and the number of solvent molecules are known as colligative properties. Some of the colligative properties are: depression in freezing point, elevation in boiling point, osmotic pressure.

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.
