Resumen de Lewis Structures of Oxygen Compounds of 3p-5p Nonmetals
Experimentally determined structures of oxides, oxoacids, and oxoanions of the 3p through 5p nonmetals (phosphorus, arsenic, sulfur, selenium, tellurium, chlorine, bromine, iodine, and xenon) have terminal oxygen bonds consistently shorter (by 0.2-0.3 Angstroms) than the accepted singly bonded oxygen distances. The simplest and best Lewis structures show doubly bonded terminal oxygen for all these compounds.
