The given statements associated with an electron in a hydrogen atom which is excited from the ground state to the n = 4 state should be checked. Concept Introduction: Absorption refers to how much light can be taken in by the material being measured. When electromagnetic radiation interacts with matter, atoms and molecules may absorb energy and reach to a higher energy state. With higher energy, these are in an unstable state. For returning to their normal (more stable, lower energy) energy state, the atoms and molecules emit radiations in various regions of the electromagnetic spectrum. The spectrum of radiation emitted by a substance that has absorbed energy is called an emission spectrum .

a) Under acidic conditions, H3PO4 can be reduced into H3PO3 directly (-0.28V), or via the
formation and reduction of H4P2O6 (-0.93/+0.38V). Calculate the values of AG's for both
processes; comment.

These two reactions appear to start with the same starting materials but result in different products. How do the chemicals know which product to form? Are both products formed, or is there some information missing that will direct them a particular way?
What would be the best choices for the missing reagents 1 and 3 in this synthesis?
1. PPh3

2. n-BuLi
• Draw the missing reagents in the drawing area below. You can draw them in any arrangement you like.
• Do not draw the missing reagent 2. If you draw 1 correctly, we'll know what it is.
• Note: if one of your reagents needs to contain a halogen, use bromine.
