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,...

Khan Academy: Simple and Compound Sentences
A simple sentence contains one independent clause. A compound sentence contains more than one! Put another way: a simple sentence contains a subject and a predicate, but a compound sentence contains more than one subject and more than...

Khan Academy: Common and Systematic Naming Prefixes
There is a logical system in which to name carbon chains as described here. The naming system becomes more logical when there are more than five compounds in the chain. Understand the prefixes: iso-, sec- and tert-. [13:29]
