L ligands are derived from charge-neutral precursors and are represented by amines, phosphines, CO, N 2, and alkenes. A single molecule of ethylenediamine can form two bonds to a metal ion. Twenty-five rats of each sex and 50 mice of each sex were placed on test as controls. (b) is an example where ethylenediamine acts as a ligand. X ligands typically are derived from anionic precursors such as chloride but includes ligands where salts of anion do not really exist such as hydride and alkyl. Ethylenediamine possesses two N groups, which each contain a lone pair of electrons, that can attach to a metal ion. Because en is diprotic, the titration curve has two equivalence points; the first equivalence point is reached when nM HClH== Cl VM HCle en Vn ne= n where n is the moles of HCl or of en; thus.
