A) \[N{{O}_{2}}\]
B) \[Mn{{O}_{2}}\]
C) \[Ba{{O}_{2}}\]
D) \[S{{O}_{2}}\]
Correct Answer: C
Solution :
[c] \[Ba{{O}_{2}}\] is the peroxide A peroxide is a compound containing an O - O single bond or peroxide anion,\[O_{2}^{2-}\] simplest stable peroxide is hydrogen peroxide. In \[Ba{{O}_{2}}\], two oxygen atoms are linked by a single bond. From\[Ba{{O}_{2}}\], \[{{H}_{2}}{{O}_{2}}\] can be formed in laboratory While\[Pb{{O}_{2}}\], and\[Mn{{O}_{2}}\] are may be mistaken as peroxide as they do not give\[{{H}_{2}}{{O}_{2}}\], on treatment, do not contain\[O_{2}^{2-}\].\[\therefore \,Ba{{O}_{2}}\] is true peroxide.
