Aldehyde and Ketone Reactions - Hydrates, Acetals, & Imines: Crash Course Organic Chemistry
We’ve already learned the basics of carbonyl chemistry and talked about how we can synthesize aldehydes and ketones, but there’s still so much more to learn, like the role carbonyl groups play in reactions involving sedatives! In this...

Stereochemistry: Meso Compounds, Diastereomers
Defining meso compounds, inversion centers, and diastereomers.

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!
Professor Dave Explains
Practice Problem: Hydrogenation, Isomerism, and Cyclohexane Chairs
For this one we need to understand the stereospecificity of hydrogenation over platinum metal, stereochemical relationships, and the relative stability of cyclohexane chair conformations.

Khan Academy: Diastereomers and Meso Compounds: Stereoisomers, Enantiomers,
This video looks at pairs of molecules to see if they relate to each other in obvious or less than obvious ways, for example, by having the same molecular formula but different structures. The video looks at stereoisomers, enantiomers,...
