MCQ
Number of molecules/species from the following having one unparred electron $15$. . . . . . $\mathrm{O}_2, \mathrm{O}_2^{-1}, \mathrm{NO}, \mathrm{CN}^{-1}, \mathrm{O}_2^{2-}$
- A$1$
- ✓$2$
- C$3$
- D$4$
$\mathrm{O}_2 \rightarrow$ no. of unpaired electrons $=2$
$\mathrm{O}_2^{-} \rightarrow$ no. of unpaired electron $=1$
NO $\rightarrow$ no. of unparred electron $=1$
$\mathrm{CN}^{-} \rightarrow$ no. of unparred electron $=0$
$\mathrm{O}_2^{2-} \rightarrow$ no. of unpaired electron $=0$
