WebDehydration of Alcohols to Yield Alkenes. One way to synthesize alkenes is by dehydration of alcohols, a process in which alcohols undergo E1 or E2 mechanisms to lose water and form a double bond. The 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, … Despite the common features, the reactivity of alkyl halides is opposite in E2 and SN2 reactions. In E2 reactions, it increases with the number of alkyl groups on the substrate – the more substituted, the more reactive: Remember, on the other hand, that SN2 is favored for less substituted alkyl halides as the … See more We have seen above that the base appears in the rate equation of E2 reactions: This means the rate of the E2 reaction increases with the concentration and the strength of the base. The list of common strong … See more Just like in any substitution and elimination reaction, the bond to the leaving group is partially broken in the transition state. Therefore, in E2 reactions as well, the better the leaving group, the faster the E2 reaction. The most … See more As we discussed above, the stronger the base, the faster the E2 elimination occurs. Therefore, polar aprotic solvents increase the rate of E2 reactions. This is because polar aprotic solvents do not interact with the base (no … See more fnb platinum business card
