Super Oxide:- A superoxide is a compound that contains the superoxide ion , which has the chemical formula O −2 The systematic name of the anion is dioxide(1−) . The r eactive oxygen ion superoxide is particularly important as the product of the one-electron reduction of Dioxygen O 2 , which occurs widely in nature. Molecular oxygen (dioxygen) is a diradical containing two unpaired electrons , and superoxide results from the addition of an electron which fills one of the two degenerate molecular structure , leaving a charged ionic species with a single unpaired electron and a net negative charge of −1. Both dioxygen and the superoxide anion are free radicals that exhibit paramagnetism. Superoxide forms salts with alkali metals and alkaline earth metals . The salts CsO 2 , RbO 2 , KO 2 , and NaO 2 are prepared by the reaction of O 2 ...
