Maximum bond angle at nitrogen is present in which of the following?

1. $\mathrm{N}{\mathrm{O}}_2$
2. ${\mathrm{N}\mathrm{O}}_2^{-}$
3. ${\mathrm{N}\mathrm{O}}_2^{+}$
4. ${\mathrm{N}\mathrm{O}}_3^{-}$

Solution

${\text{NO}}_2=$
${\text{NO}}_2^{-}=$
${\text{NO}}_3^{-}=$
${\mathrm{N}\mathrm{O}}_2^{+}$ ion $\Rightarrow$
$\mathrm{H}=\frac{1}{2}\left(5-1\right)=2\mathrm{ }\left(\mathrm{s}\mathrm{p}\mathrm{ }\mathrm{h}\mathrm{y}\mathrm{b}\mathrm{r}\mathrm{i}\mathrm{d}\mathrm{i}\mathrm{s}\mathrm{a}\mathrm{t}\mathrm{i}\mathrm{o}\mathrm{n}\right)$
Linear geometry

Bond angle ${180}^{\mathrm{o}}$
