Decreasing order of stability of straight O subscript 2 comma space straight O subscript 2 superscript minus comma space straight O subscript 2 superscript plus comma space and space straight O subscript 2 superscript 2 minus end superscript is

  • straight O subscript 2 superscript plus space greater than space straight O subscript 2 space greater than space straight O subscript 2 superscript minus space greater than space straight O subscript 2 superscript 2 minus end superscript
  • straight O subscript 2 superscript 2 minus end superscript space greater than space straight O subscript 2 superscript minus space greater than space straight O subscript 2 space greater than space straight O subscript 2 superscript plus
  • straight O subscript 2 space greater than straight O subscript 2 superscript plus space greater than space straight O subscript 2 superscript 2 minus end superscript space greater than thin space straight O subscript 2 superscript minus
  • straight O subscript 2 superscript minus space greater than thin space straight O subscript 2 superscript 2 minus end superscript space greater than thin space straight O subscript 2 superscript plus space greater than thin space straight O subscript 2

Solution

A.

straight O subscript 2 superscript plus space greater than space straight O subscript 2 space greater than space straight O subscript 2 superscript minus space greater than space straight O subscript 2 superscript 2 minus end superscript

order of stability directly proportional to the bond order
therefore, the order of the stability of given species,
stack space space with Bond space order below space space space stack straight O subscript 2 superscript plus with 2.5 below space greater than stack space straight O subscript 2 space with 2 below greater than stack space straight O subscript 2 superscript minus with 1.5 below space greater than space stack straight O subscript 2 superscript 2 minus end superscript with 1 below
