Which of the following are arranged in an increasing order of their bond strengths ?

Options

  1. AO ₂⁻ < O ₂ < O ₂⁺ < O ₂²⁻
  2. BO ₂²⁻ < O ₂⁻ < O ₂ < O ₂⁺
  3. CO ₂⁻ < O ₂²⁻ < O ₂ < O ₂⁺
  4. DO ₂⁺ < O ₂ < O ₂⁻ < O ₂²⁻

Correct answer

B. O ₂²⁻ < O ₂⁻ < O ₂ < O ₂⁺

Step-by-step solution

According to bond order values the given order is the answer. Bond order values are +1,+1 1 2 ,+2 and +2 1 2 , higher bond order means stronger bond.
