$(II)\, O^+_2 ,NO,N^-_2$ have same bond order of $2 \frac{1}{2}$
$(III)$ Bond order can assume any value including zero upto four
$(IV)\, NO^-_3$ and $BO^-_3$ have same bond order for $X - O$ bond (where $X$ is central atom)
$\begin{array}{*{20}{c}}

{|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\
{\,C{H_3}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,}
\end{array}$ is

$C{H_3} - C \equiv C - H\xrightarrow{{NaN{H_2}}}\xrightarrow{{C{H_3} - I}}(A)\xrightarrow{{Li/liq\,N{H_2}}}(B)$
$C{H_3} - C \equiv C - H\xrightarrow{{NaN{H_2}}}\xrightarrow{{C{H_3} - I}}(A)\xrightarrow[{Pd.CaC{O_3}}]{{{H_2}}}(C)$
