WebE2, possibly some SN1. E2. Weak (reaction with H2O or R’OH) SN1, possibly E1. E1. Note that some anionic nucleophiles are less basic than ¯OH/OR’, such as acetate CH 3 COO¯ (weakly basic) or iodide (non-basic). These will tend to give more substitution and much less elimination.

[E2] or R+ [E1] Nucleophile or Base? most nucleophiles are also bases (and vice versa) to favor elimination: use a strong, hindered base e.g., KOtBu to favor substitution: use a small, unhindered nucleophile how did persia startWebmore. In a substitution reaction an existing group on the substrate is removed and a new group takes its place. In an elimination reaction the group is simply removed and no new group comes to take its place and this usually results in a double or triple bond forming in the substrate instead. Hope that helps.

WebS N 1/E1: It is hard to separate SN1 and E1 completely because they both go through carbocation intermediates and are favored by a poor nucleophile/weak base, for example, H 2 O or ROH (solvolysis). Under such neutral conditions, S N 1 and E1 usually occur together for secondary substrates, and increasing the reaction temperature favors E1 … Web- Réaction intramoléculaire : réaction d’élimination (E1) et formation d’un alcène Règle de Zaïtsev : le 𝐻 partant est celui situé sur le carbone le plus substitué, donc le moins hydrogéné Exemple avec le 2-méthylbutan-2-ol : - Réaction intermoléculaire : réaction de substitution et formation d’un éther-oxyde à 120°C

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.

E1 reactions are a Unimolecular Elimination Mechanism, which means the rate-determining step is the dissociation of the leaving group to form a carbocation. Since E2 is bimolecular and the nucleophilic attack is a part of the rate-determining step, a weak base/nucleophile disfavors it (E2) and ultimately allows E1 to dominate.
