As a result, the anion that has more electron density is more nucleophilic. Since fluorine is more electronegative than iodine, the fluoride anion is more electron dense than iodide. In aprotic solvents, nucleophilicity correlates to basicity. gainly hk

"In chemistry, a nucleophile is a chemical species that forms bonds by donating an electron pair. All molecules and ions with a free pair of electrons or at least one pi bond can act as nucleophiles. Because nucleophiles donate electrons, they are Lewis bases. Nucleophilic describes the affinity of a nucleophile to bond with positively char… " - Oh- nucleophile
