Number of molecules/species from the following having one unpaired electron is \(\qquad\) \(\mathrm{O}_2,…
Number of molecules/species from the following having one unpaired electron is \(\qquad\) \(\mathrm{O}_2, \mathrm{O}_2^{-1}, \mathrm{NO}, \mathrm{CN}^{-1}, \mathrm{O}_2^{2-}\)
Solution
According to M.O.T.
$\mathrm{O}_2 \rightarrow$ no. of unpaired electrons $=2$
$\mathrm{O}_2^{-} \rightarrow$ no. of unpaired electron $=1$
$\mathrm{NO} \rightarrow$ no. of unpaired electron $=1$
$\mathrm{CN}^{-} \rightarrow$ no. of unpaired electron $=0$
$\mathrm{O}_2^{2-} \rightarrow$ no. of unpaired electron $=0$
