Stereochemistry of elimination reaction
網頁2024年1月20日 · The E1 elimination reaction consists of two steps. The first step is the slow step also the rate-determining step whereas, the second step is the fast step. Further, E1 reactions are analogous to the SN1 reaction that why compete with nucleophilic substitution (S N 1) reactions. Tertiary alkyl halides give E1 elimination reactions. 網頁Stereochemistry of the E2 Reaction E2 elimination reactions of certain isomeric cycloalkyl halides show unusual rates and regioselectivity that are not explained by the …
