An oxyanion, or oxoanion, is an ion with the generic formula A xO y (where A represents a chemical element and O represents an oxygen atom). Oxyanions are formed by a large majority of the chemical elements. The formulae of simple oxyanions are determined by the octet rule. The … Meer weergeven The formula of monomeric oxyanions, AO n, is dictated by the oxidation state of the element A and its position in the periodic table. Elements of the first row are limited to a maximum coordination number of 4. However, … Meer weergeven In aqueous solution, oxyanions with high charge can undergo condensation reactions, such as in the formation of the dichromate ion, … Meer weergeven The pKa of the related acids can be guessed from the number of double bonds to oxygen. Thus perchloric acid is a very strong acid while hypochlorous acid is very weak. A simple rule usually works to within about 1 pH unit. Meer weergeven • Oxycation • Fluoroanion • Carbanion Meer weergeven A polyoxyanion is a polymeric oxyanion in which multiple oxyanion monomers, usually regarded as MOn polyhedra, are joined by sharing corners or edges. When two corners of a polyhedron are shared the resulting structure may be a chain or a ring. Short … Meer weergeven Most oxyanions are weak bases and can be protonated to give acids or acid salts. For example, the phosphate ion can be successively protonated to form phosphoric acid. The extent of protonation in aqueous solution will … Meer weergeven WebThe crotonases comprise a widely distributed enzyme superfamily that has multiple roles in both primary and secondary metabolism. Many crotonases employ oxyanion hole-mediated stabilization of intermediates to catalyze the reaction of coenzyme A (CoA) thioester substrates (e.g., malonyl-CoA, α,β-unsaturated CoA esters) both with nucleophiles and, …
