Sn1 is regioselective
WebThe SN1 reaction is a two-step unimolecular process with one intermediate and two transition states. Leaving group ability increases with decreasing basicity. The addition of … WebThe dehydration reaction of alcohols to generate alkene proceeds by heating the alcohols in the presence of a strong acid, such as sulfuric or phosphoric acid, at high temperatures. The required range of reaction temperature decreases with increasing substitution of the hydroxy-containing carbon: 1° alcohols: 170° - 180°C.

Web19 Nov 2016 · Regioselectivity is the preference for one orientation over another in the arrangement of a reaction product. Explanation: Regiochemisry in alkene addition reactions refers to which part the reagent adds to which part of the double bond. This is also called the "orientation of addition." Web2 Jul 2010 · The major product is where addition has occurred on the most substituted carbon. The mechanism doesn’t rule out a small amount of the minor structural isomer. (Note that this reaction as shown, forms a 50:50 mixture of enantiomers. It is regioselective, but not enantioselective.)
