Web28 May 2024 · 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. Is hydrogenation a stereospecific? 4. WebThe Zaitsev’s and Hoffman’s rules demonstrate the principle of regioselectivity in elimination reactions. Regioselective means that the reaction selectively produces one regioisomer as the major product. The two alkenes are regioisomers since the double bonds are in …
