E1 reaction chart
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. WebSecondary (2°) It is most complicated or challenging to predict the reaction of a secondary substrate (2°) because all the pathways are possible. The reaction conditions then …

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.
