Web4. Under many circumstances, I would agree that bromide is a better nucleophile than water. It's negatively charged and, due to its size, bromine is more polarizable than oxygen. … Web(X = Cl, Br, or I) The product-determining step involves the partitioning of this intermediate between two paths: one is the reaction with water and the other is loss of a proton: ... 6 The first reaction involves a strong nucleophile (CH 3 O–), and the SN2 mechanism is favored. Therefore, only one product is obtained.
Is Br or Cl A better nucleophile in water? - KnowledgeBurrow
WebIn a molecule like CH₃CH₂-Br, Br is more electronegative than C, so C-1 has a partial positive (δ⁺) charge. The lone pair on the N can attack the δ⁺ carbon on CH₃CH₂Br: H₃N: + Br … 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.

Also note that the hydration effect on the Br- may actually be greater as it is in the form of ion-dipole interactions, which are likely stronger than the hydrogen bonding interactions between water molecules. $\endgroup$ – raftaci online bombuj
