Regioselectiviy occurs in chemical reactions where one reaction site is preferred over another. For example, the addition of an asymmetric reagent (such as H-Cl) to an asymmetric alkene may yield two different products. The reaction is regioselective if one of the two products is preferred over the other. Markovnikov additions are common examples of regioselective reactions.
