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 O₂^2-. 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

The bond order for O2 is 2, calculated as (10 bonding electrons - 6 antibonding electrons)/2. For O2^2-, the bond order is 1, calculated as (10 bonding electrons - 8 antibonding electrons)/2.
