Question

In how many of the following sequences magnetic behaviour & bond order changes after each step.

(i) $N_{2} \to N_{2}^{⊖} \to N_{2}^{+} \to N_{2}^{- 2}$

(ii) $O_{2} \to O_{2}^{+ 2} \to O_{2}^{- 2} \to O_{2}^{- 1}$

(iii) $C_{2} \to C_{2}^{- 2} \to C_{2}^{+ 2} \to C_{2}$

(iv) $B_{2} \to B_{2}^{+ 3} \to B_{2}^{- 1} \to B_{2}^{+ 1}$

(v) $Li_{2} \to Li_{2}^{+ 1} \to Li_{2}^{+ 2} \to Li_{2}^{- 1}$
