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. WebErnest Zinck. 7 years ago. SN1 and E1 — the leaving group leaves first. SN2 and E2 — the leaving group leaves last. SN1 and SN2 — the X:⁻ attacks a carbon atom. E1 and E2 — the X:⁻ attacks a β hydrogen atom. ( 11 votes)
