Concept:In coordination compounds, ligands can be neutral, positively charged, or negatively charged.Explanation:Ammonia is $\mathrm{NH_3}$, which is a neutral ligand.Methylamine is $\mathrm{CH_3NH_2}$, which is also a neutral ligand.Hydrazinium is $\mathrm{N_2H_5^+}$, which carries a positive charge.Nitrate is $\mathrm{NO_3^-}$, which carries a negative charge.Therefore, among the given options, the negative ligand is nitrate.Answer:Option D: Nitrate $\left(\mathrm{NO_3^-}\right)$
