Question

Nucleophilicity of halide ions in acetone solution

Answer 1

Answer:

When talking about elements of a group, the size of the atom is more effective than the electronegativity factor. As F− size is too short so its electron density will be much higher than other hallogens.

In aprotic solvent the order of nucleophillicity: F−>Cl−>Br− >I−(No hydration occurs) In protic solvant(like H2O) its reversed because of hydration of ions having much electron density.
