Is br or cl a stronger nucleophile
WebJan 2, 2024 · These results indicate that bromide is the stronger nucleophile due to its slightly higher percentage in the Sn1 reaction. Bromide’s greater nucleophilicity, aqueous solvent effects, (wherein chloride was caged by water), and rate law kinetics all contributed to an 8:1 difference in product ratios for the Sn2 reaction. REFERENCES WebHence, the nucleophilicity of Br - is more than Cl -. b. On proceeding down the group in the periodic table, basicity decreases and nucleophilicity decreases. Chlorine is situated …

WebThe thiol group in a cysteine amino acid, for example, is a powerful nucleophile and often acts as a nucleophile in enzymatic reactions, and of course negatively-charged thiolates (RS -) are even more nucleophilic. This is not to say that the hydroxyl groups on serine, threonine, and tyrosine do not also act as nucleophiles - they do. WebDec 3, 2014 · The result is that the nucleophile has few molecules in its solvent shell. The nucleophile can more easily attack the substrate. F⁻ becomes a much better nucleophile. In polar aprotic solvents, the order of nucleophilicity is reversed: F⁻ > Cl⁻ > Br⁻ > I⁻ Answer link
