WebDec 13, 2009 · The Attempt at a Solution. I'm really confused because in my book, it says that in protic solvents, the larger atoms (I-) are stronger nucleophiles than smaller ones (F-). Then it says that it is opposite for when it is an aprotic solvent (e.g. F- is more nucleophilic than I-) In this case, the answer to b) is H2S and c) is (CH3)3P, but shouldn ... WebCharge is the most important factor, so we expect negatively charged acetate to be a better nucleophile than NH3. So yes, it is a good one. (Electronegativity and resonance, you'll notice, both work to weaken the nucleophilicity of acetate - but since charge is more important, the overall result is still a good nucleophile.) Let's do iodine now.
Webnucleophile and the R-group, with its partial The X-group is the leaving group and leaves with the two electrons in the R-X bond. The new R-Y bond is formed with the two electrons that come from the nucleophile Y. The nucleophile, by definition, donates two electrons to the electrophile. In order to be a nucleophile, it must have two electrons ... WebHydrogen sulfide is a flammable, colorless gas with a characteristic and often nauseating odor of rotten eggs at low concentrations. It is heavier than air (d = 1.19) at standard …
WebReactions with Nitrogen Nucleophiles. There is a similarity between the reactions of oxygen nucleophiles and nitrogen nucleophiles. For example, let us look at the reaction of a primary amine with a ketone. The mechanism begins in the same way with the nucleophile(N) attacking the carbonyl to form a tetrahedral intermediate, which can … WebJun 11, 2024 · In SN1, nucleophilicity is irrelevant, since the nucleophile doesn't appear in the rate determining step, but I'd imagine the equilibrium position can be roughly estimated by relative leaving group abilities. In answer to your specific example, fluoride would actually be a poorer SN2 nucleophile than you might think, worse than the bromide ...
Webmost 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 …
