Question
Which of the following is a true peroxide?(a) $\mathrm{BaO}_{2}$(b) $\mathrm{SO}_{2}$(c) $\mathrm{NO}_{2}$(d) $\mathrm{MnO}_{2}$
Step 1
(a) BaO2: This is barium peroxide, which has the formula Ba(O2) and contains the O-O bond. The oxidation state of each oxygen atom is -1. So, this is a true peroxide. (b) SO2: This is sulfur dioxide, which has the formula SO2 and does not contain the O-O bond. Show more…
