Question

Both length order is

Options

A.O₂ < O₃ < O₂^2-

B.O₂ < O₂^2- < O₃

C.O₂^2- < O₃ < O₂

D.O₂ = O₂^2- < O₃

Solution

Bond length is inversely proportional to bond order. Bond order of O₂, O₃ and O₂^2- are 2, 1.5 and 1 respectively. Hence the correct sequnce of bond lengths is O₂ < O₃ < O₂^2-
