Stereochemistry is very important when we talk about aliphatic addition reactions.
Regioselectivity: This term means the way the addition happens can lead to different outcomes. For instance, when HBr adds to propene, we follow Markovnikov’s rule. This rule says that hydrogen will add to the carbon that has fewer substitutes. This helps us predict which product we will get.
Stereoselectivity: This is about how the reaction can create different forms of products called stereoisomers. When we add hydrogen to alkenes, we can get either cis or trans products. These forms have different physical traits.
Example: When bromine is added to cyclopentene, we can get different forms. There are both meso and optically active versions because of how the reactants are arranged. This affects the overall mix of products we get.
Knowing these ideas is important for predicting how reactions work in organic chemistry.
