WebOct 11, 2024 · In an oxyanionic polymerization, glycidol as a latent AB 2 monomer is copolymerized with the protected linear AB glycidyl ether monomer EEGE (ethoxy ethyl glycidyl ether) to generate hyperbranched polyglycerols with an adjustable degree of branching (DB) after deprotection. The DB for the random copolymers is controlled by the … 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 corresponding … See more 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, none of … See more In aqueous solution, oxyanions with high charge can undergo condensation reactions, such as in the formation of the dichromate ion, … See more 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. See more • Oxycation • Fluoroanion • Carbanion See more 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 chains … See more 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 depend … See more
