Number of molecules/species from the following having one unpaired electron is (\qquad) (\mathrm{O}_2, \mathrm{O}_2^{-1}, \mathrm{NO}, \mathrm{CN}^{-1}, \mathrm{O}_2^{2-})

Correct answer

2

Step-by-step solution

According to M.O.T. O2→\mathrm{O}_2 \rightarrow no. of unpaired electrons =2=2 O2−→\mathrm{O}_2^{-} \rightarrow no. of unpaired electron =1=1 NO→\mathrm{NO} \rightarrow no. of unpaired electron =1=1 CN−→\mathrm{CN}^{-} \rightarrow no. of unpaired electron =0=0 O22−→\mathrm{O}_2^{2-} \rightarrow no. of unpaired electron =0=0
