MCQ
The compound which does not possess a peroxide linkage is
  • A
    $N{a_2}{O_2}$
  • B
    $Cr{O_5}$
  • C
    ${H_2}S{O_5}$
  • ✓
    $Pb{O_2}$
✓

Correct option: D.
$Pb{O_2}$
d
A peroxide is a compound containing an oxygen-oxygen single bond or the peroxide anion The $O - O$ group is called the peroxide group or peroxo group.
