Which of the following has least bond energy?

Step-by-step solution

aligned N ₂²⁻=K K^ 2 s², 2 s², 2 p_ z ², 2 p_ x ², & 2 p_ y ² & 2 p_ x ² aligned aligned Bond order &= N_ b -N_ a 2 &= 8-4 2 =2 aligned (b) N ₂⁻=K K^ 2 ~s ², 2 ~s ², 2 p_ z ², 2 p_ x ²= 2 p_ y ² Bond order = 8-3 2 =2.5 (c) N ₂⁺=K K^ 2 s² 2 s², 2 p_ x ²= 2 p_ y ², 2 p_ z ¹ Bond order = 7-2 2 =2.5 (d) N ₂=K K^ 2 s², ^ 2 s², 2 p_ x ²= 2 p_ y ², 2 p_ z ² Bond order = 8-2 2 =3 Bond energy 1 Bond order N ₂ has least bond energy.
