Question

Which species is diamagnetic and has a bond order of 3?

Options

Choose one · Correct answer highlighted

Explanation

For N₂ (14 electrons): (sigma 1s)² (sigma^* 1s)² (sigma 2s)² (sigma^* 2s)² (pi 2px)² (pi 2py)² (sigma 2pz)². Bonding = 10, antibonding = 4. Bond order = (10 - 4/2) = 3, with all electrons paired, making it diamagnetic.
