In E2, elimination shows a second order rate law, and occurs in a single concerted step (proton abstraction at C α occurring at the same time as C β-X bond cleavage). In E1, elimination goes via a first order rate law, …

WebNo, 2° substrates can react via SN1 or SN2, depending on the conditions. We have two competing processes. If the nucleophile attacks faster than the leaving group spontaneously leaves, the reaction is SN2. If the leaving group leaves before the nucleophile can successfully attack, we have SN1. WebDec 15, 2024 · The reaction between tert -butylbromide and water proceeds via the SN1 mechanism. Unlike S N 2 that is a single-step reaction, S N 1 reaction involves multiple steps. Reaction: (CH 3) 3 CBr + H 2 O → (CH 3) 3 COH + HBr. In step 1, C—Br bond breaks and Br departs with the bonding electron pair to produce a tertiary carbocation …
