Consider the general alkene addition reaction:

R1R2C=CR3R4 + XY ---->

How many stereoisomers are possible for the original alkene?

How many regioisomers (constitutional isomers) are possible for the addition product?

How many stereoisomers are possible for each of the product regioisomers?

If any of your answers are "it depends", what does it depend on?
