WebAlkene and alkyne ligands. An alkene ligand contains a π bond between carbon atoms, C=C, which can serve as an electron pair donor in a metal complex, as in the case of Zeise’s salt (see above Historical developments).This complex may be prepared by bubbling ethylene, C 2 H 4, through an aqueous solution of [PtCl 4] 2− in the presence of divalent tin, Sn(II), … Phenols are more acidic than typical alcohols. The acidity of the hydroxyl group in phenols is commonly intermediate between that of aliphatic alcohols and carboxylic acids (their pKa is usually between 10 and 12). Deprotonation of a phenol forms a corresponding negative phenolate ion or phenoxide ion, and the corresponding salts are called phenolates or phenoxides (aryloxides according …
