Which ion is the strongest nucleophile in aqueous solution?

Question

Quizplus · Accepted Answer

Iodide (I-) is the strongest nucleophile among the halide ions due to its large size and high polarizability. In aqueous solution, it is still a strong nucleophile because water can act as a weak acid, increasing the relative nucleophilicity of the anions. Fluoride (F-) is the weakest nucleophile due to its small size and high electronegativity, which makes it less polarizable and less likely to participate in nucleophilic reactions.
