The normal oxide contains ________ ion, peroxide contains _______ ion and superoxide contains ___ ion.

A

O2−,O22−,O2−O^{2 -},O_{2}^{2 -},O_{2}^{-}

B

O2−,O2−,O22−O^{2 -},O_{2}^{-},O_{2}^{2 -}

C

O−,O2−,O3−O^{-},O^{2 -},O^{3 -}

D

O−,O2−,O22−O^{-},O^{2 -},O_{2}^{2 -}

Answer

O2−,O22−,O2−O^{2 -},O_{2}^{2 -},O_{2}^{-}

Explanation

Solution

: Normal oxide contains O2−O^{2 -} ion, peroxide contains O22−[−O−O−]2−O_{2}^{2 -}\lbrack - O - O - \rbrack^{2 -} ion and superoxide contains O2−[:O..−−틿O..−O_{2}^{-}\lbrack:\overset{..}{O}\overset{틿}{- -}{\overset{..}{O}}^{-}ion.
