E1 v e2 reaction
Did you know?
WebThe main difference between the E1 and E2 reactions is their number of steps. The E1 reaction takes place in two steps and has a carbocation intermediate. In contrast, the E2 reaction takes place in one step and has no intermediate. Thus, E1 is a first-order reaction, while E2 is a second-order reaction requiring an anti periplanar geometry WebTable of Contents For E1 reaction For E2 reaction The Zaitsev Rule With E1 and E2 mechanisms we have already met, but let’s compare them now. Both are elimination reactions. When alkyl halides react with bases, the halides and hydrogen of the adjacent carbon are eliminated, and alkenes are obtained. If we have simpler alkyl halides, we …

Similarly, tertiary sulfonates have been observed to undergo E2 reactions when treated with strong bases and to undergo unimolecular reactions (SN1 and E1) in protic solvents."
