Vedclass · Answer

(B) ligand is an ion or molecule that binds to a central metal atom or ion to form a coordination complex. The essential requirement for a species to act as a ligand is the presence of at least one lone pair of electrons to donate to the metal center.$1$. $NO$ (Nitric oxide) has a lone pair on the nitrogen atom and can act as a ligand.$2$. $NH_4^+$ (Ammonium ion) has all its valence electrons involved in covalent bonding with hydrogen atoms. It has no lone pair of electrons to donate,so it cannot act as a ligand.$3$. $H_2N-CH_2-CH_2-NH_2$ (Ethylenediamine) has lone pairs on both nitrogen atoms and acts as a bidentate ligand.$4$. $CO$ (Carbon monoxide) has a lone pair on the carbon atom and acts as a ligand.Therefore,$NH_4^+$ is not expected to be a ligand.

Which of the following species is not expected to be a ligand?
