This video provides an overview of the stereochemistry of organic compounds and defines what exactly a chiral carbon center is.  This video also shows you how to assign R and S configuration to a chirality center whenever the hydrogen (4th group) atom is in the front, back, or neither.  It also discusses nomenclature - how to name organic compounds using R and S absolute configuration.  It provides a lot of examples and practice problems.  Finally, this video discusses how to classify a pair of molecules or compounds as diastereomers, enantiomers, meso compounds, constitutional isomers, same compound, or different compounds, or even cis trans geometric isomers.

Great but I don't understand 47:25.. 2 Br groups - one facing in and 1 facing out. For that reason are they not considered as different such as in the other examples when they are in a ring. or is it different because it's an alline?

My professor tried to explain this concept over a prerecorded lecture.. needless to say, your knowledge and collected mode of explanation should be utilized in all orgo classes! thank you so much
