Which mechanism causes increased bond strength when diatomic nitrogen forms N₂⁺?

A)Removing an antibonding electron
B)Increasing nuclear repulsion energy
C)Decreasing electron kinetic energy
D)Shortening the bond vibrational wavelength

💡 Explanation

Removing an electron from an antibonding molecular orbital strengthens the nitrogen-nitrogen bond because the overall antibonding character is reduced. Therefore, the bond order increases, rather than decreasing it or affecting separate properties.
