- A$NO_3^ - $
- B$NO_2^ - $
- C$N{O_2}$
- ✓$NO_2^ + $
increase of electron or increase of more electronegative atom in it decrease its bond angle since $NO_2^ + $ loose a electron by which its bond angle increase from $132^o$.

Statement $II :$ As the size of the elements $\mathrm{F}, \mathrm{Cl}, \mathrm{Br}, \mathrm{I}$ increases down the group, the bond strength of $\mathrm{HF}$, HCl, HBr and HI decreases and so the acid strength increases.
In the light of the above statements, choose the correct answer from the options given below.
$O _{2}^{+}, O _{2}, O _{2}^{-}, O _{2}^{2-}$
For increasing bond order the correct option is ..... .
${P_4}\xrightarrow{{{O_2}}}'X'$
${P_4}\xrightarrow{{{O_2}(excess)}}'Y'$
Statement $I$ : The electronegativity of group $14$ elements from $\mathrm{Si}$ to $\mathrm{Pb}$ gradually decreases.
