WebDec 15, 2024 · The total four types of reactions can be separated into 3 pathway, that is: E2: favored by a strong base. SN2: favored by a good nucleophile (relatively weaker … 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.

WebWhile SN1 and SN2 reactions appear to follow the same mechanism, The ‘1’ type reaction (SN1) is a slow reaction with a carbocation intermediate. This can only occur in the presence of a weak nucleophile. The ‘2’ type … 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.
