The correct order of bond order in \(\mathrm{N}_2, \mathrm{~N}_2{ }^{2-}, \mathrm{N}_2^{-}\)is:
1 \(\mathrm{N}_2{ }^{-}<\mathrm{N}_2{ }^{2-}<\mathrm{N}_2\)
2 \(\mathrm{N}_2-\mathrm{N}_2<\mathrm{N}_2\)
3 \(\mathrm{N}_2{ }^{-}<\mathrm{N}_2{ }^{-}<\mathrm{N}_2\)
4 \(\mathrm{N}_2<\mathrm{N}_2^{2-}<\mathrm{N}_2^{-}\)
