WebSep 25, 2024 · 2) The nucleophile: powerful nucleophiles, especially those with negative charges, favor the S N 2 mechanism. Weaker nucleophiles such as water or alcohols favor the S N 1 mechanism. 3) The solvent: Polar aprotic solvents favor the S N 2 mechanism by enhancing the reactivity of the nucleophile. 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 …
