The correct order of bond strength for the given species is:

The formal charges of $N_{(1)}$,$N_{(2)}$,and $O$ atoms in the structure $N_{(1)} = N_{(2)} = O$ are respectively:

In which of the following options, the order of arrangement does not agree with the variation of property indicated against it?
$(a)$ $BF_3 < NF_3 < NH_3$ (Dipole moment)
$(b)$ $HgCl_2 > NH_4^+ > SF_6$ (Bond angle)

The correct order of strength of $\pi-$ bond$(s)$ is:
$I$. $BO_3^{-3} < CO_3^{-2} < NO_3^{-}$
$II$. $ClO_4^{-} > SO_4^{-2} > PO_4^{-3}$
$III$. $BF_3 > BCl_3 > BBr_3$
$IV$. $AlCl_3 < BCl_3$

The correct order of $O-O$ bond length in $O_{2}$, $H_{2}O_{2}$ and $O_{3}$ is
