Question

Which of the following is a super oxide?

• A. $K{O}_2$
• B. $N{a}_2{O}_2$
• C. $L{i}_{2}O$
• D. $CeO$

Answer 1

Answer: (A)

$K{O}_2$

• A superoxide is a compound that contains the superoxide anion, which has the chemical formula $O_2^{-}$ The systematic name of the anion is dioxide(1−). The reactive oxygen anion superoxide is particularly important as the product of the one-electron reduction of dioxygen $O_2$, which occurs widely in nature.
  
• Among the given options $K{O}_2$ is having $O_2^{-}$ and hence is a superoxide.
