Match the following : The correct answer is

Step-by-step solution

Bond order Number of bonding electrons - Number of antibonding electrons aligned & ( A I V ) & aligned N ₂⁺= 1 s^2 < * 1 s^2 < 2 s^2 < * 2 s^2, 2 p_x^2= & 2 p_y^2 & < 2 p_z^1 aligned aligned Bond order of N ₂⁺= 9-4 2 =25 aligned &( B V ) & CO = 1 s^2 < * 1 s^2 < 2 s^2 < * 2 s^2 < 2 p_z^2 < 2 p_x^2 &= 2 p_y^2 aligned Bond order of CO = 10-4 2 =3 aligned &( C III ) & O ₂= 1 s^2 < * 1 s^2 < 2 s^2 < * 2 s^2 < 2 p_z^2 < 2 p_x^2 &= 2 p_y^2 < ^* 2 p_x^1= ^* 2 p_y^1 aligned Bond order of O ₂= 10-6 2 =2 aligned & ( D II ) &
