WebE1: There is no specific way the molecule has to be oriented in space because the two steps of the reaction happen independently; therefore, E1 has no stereospecificity. E2: The … WebAnswer. E1 reactions are a Unimolecular Elimination Mechanism, which means the rate-determining step is the dissociation of the leaving group to form a carbocation. Since E2 is bimolecular and the nucleophilic attack is a part of the rate-determining step, a weak base/nucleophile disfavors it (E2) and ultimately allows E1 to dominate. Question 2.

Civilization and its Discontents (Sigmund Freud) Voices of Freedom (Eric Foner) WebThe ‘1’ type reaction (E1) is a slow reaction with a carbocation intermediate. This is due to reacting in the presence of a weak base that awaits the leaving group's slow departure. The ‘2’ type reaction (E2) is a fast reaction with NO intermediate. This is due to the strong base quickly attacking to kick out the leaving group.
WebThe distribution of products in E2 reaction is different to distribution of products in E1 reaction. In E1 reaction, 2-methyl-1-butene eluted out early but it had a very small area and correspondingly a very small mol%. Whereas in E2 reaction, 2-methyl-1-butene eluted out early but had an area mol% larger than that found in E1 reaction.
