Practice question

Given: Which of the following molecules has a bond order of 1 according to molecular orbital theory? These values define the system as per NCERT data. Formula: Bond order = 1/2 (10 - 8) = 1 .. This is the standard NCERT relation for this phenomenon. Substitution & Calculation: For F₂ : (sigma 1s)² (sigma^* 1s)² (sigma 2s)² (sigma^* 2s)² (sigma 2p_z)² (π 2p_x)² (π 2p_y)² (π^* 2p_x)² (π^* 2p_y)² . Result: The computed value matches the expected outcome and confirms the correct choice. Units and powers like J kg⁻¹ K⁻¹, m/s², 10⁻⁵ are properly used as per NCERT.
