Why is fluoride the most nucleophilic halide in aprotic solvents?

WebFeb 4, 2024 · ethoxide ( E t O X −) ion; ethyl thiolate ( E t S X −) ion. Now, since we know fluoride ( F X −) is stronger nucleophile than iodide ( I X −) in polar aprotic solvent, i.e. nucleophilicity parallels basicity. We should expect the alkoxide ion to be more nucleophilic than thiolate since alcohols are weaker acids than thiols. WebWhich is the strongest nucleophile in polar protic solvents?
