Practice Problem: Types of Protons
We learned about how pairs of protons can have specific relationships. They can be homotopic, enantiotopic, diastereotopic, or heterotopic. Let's apply this to some examples!

Practice Problem: Four-Reaction Pathway
We are starting with benzene, we do four reactions, and what do we get? See if you can get the right answer!
Professor Dave Explains
Practice-Problem: Three-Reaction Pathway
We've got a starting material, and we are subjecting it to a series of three reaction conditions. What do we get? See if you can find out!
