Vedclass · Answer

(D) Nucleophilicity is directly proportional to the electron density on the donor atom.For species with the same donor atom,the one with a negative charge is a stronger nucleophile than its conjugate acid because it has higher electron density.Comparing $NH_{2}^{-}$ and $NH_{3}$,$NH_{2}^{-}$ has a negative charge and a lone pair,whereas $NH_{3}$ only has a lone pair.Therefore,$NH_{2}^{-}$ is a better nucleophile than $NH_{3}$.

The correct order of nucleophilicity is $.....$ .
