E1 reaction chart
WebThe E1 elimination reaction has a two step mechanism that involves a carbocation intermediate: The first step is an ionization step, in which the leaving group breaks away β¦ 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.

WebThe yield of products in E1 reaction was 74 % and of E2 reaction is 86 %. Even though, the lower percent yield of products from the E1 path, still E1 is a more efficient method for preparing alkenes because E1 is a reversible reaction where it forms alkene via dehydration reaction and forms alcohols via hydration reaction.
