Practice-Problem: Two-Reaction Pathway
This time we have a starting material, and we are gonna do just two reactions. But it's a little tricky! See if you can figure it out.
Professor Dave Explains
Practice Problem: Oxidizing Agents
For this one we need to know the ability of different oxidizing agents to react with various functional groups, and what functional groups will result.

Ramberg-Bäcklund Reaction
Let's hit one more olefination reaction, the Ramberg-Bäcklund reaction. This one involves an extrusion of sulfur dioxide to yield an olefin in intramolecular fashion. This is an example of a cheletropic reaction. Let's check out the...

The 18 Electron Rule for Transition Metal Complexes
Ok, so we understand how ligands bond to metals to form transition metal complexes, but how many ligands will fit? Well, remember the octet rule from general chemistry? There is a similar concept that we can apply here, which is called...
