    Which one of the following is an example of a true peroxide?

    A) \[N{{O}_{2}}\]                                  

    B) \[Mn{{O}_{2}}\]

    C)  \[Ba{{O}_{2}}\]                               

    D) \[S{{O}_{2}}\]

    Correct Answer: C

    Solution :

                     Barium peroxide\[(Ba{{O}_{2}})\]is an example of a true peroxide because it contains peroxide ion\[(O_{2}^{2-})\]or\[{{\left[ -O-O- \right]}^{2-}}\]and gives\[{{H}_{2}}{{O}_{2}}\]when reacts with acids. \[Ba{{O}_{2}}+{{H}_{2}}S{{O}_{4}}\xrightarrow[{}]{{}}BaS{{O}_{4}}+{{H}_{2}}{{O}_{2}}\]
