Use energy levels of diatomic molecules derived from molecular orbital theory to predict the bond order of the oxygen molecule O₂ and the peroxide anion O₂²^-. A) oxygen (bond order = 2); peroxide (bond order = 3) B) oxygen (bond order = 2); peroxide (bond order = 2) C) oxygen (bond order = 4); peroxide (bond order = 4) D) oxygen (bond order = 4); peroxide (bond order = 5) E) oxygen (bond order = 2); peroxide (bond order = 1)

Question

Quizplus · Accepted Answer

Oxygen (O2) has a bond order of 2, calculated as (10-6)/2 = 2. The peroxide anion (O2^2-) has a bond order of 1, calculated as (10-8)/2 = 1.
