Question

The bond order of the underlined species $NOHS{O}_4$ is

Answer 1

$\text{The bond order of the underlined species}NOHS{O}_4$ is $3.$

$NOHS{O}_4\text{exists as}N{O}^{+}\text{and}HS{O}_4^{-},N{O}^{+}\text{is derivative of oxygen and isoelectronic with}{O}_2^{2+}\text{Bond order is}$$\frac{(10-4)}{2}=3$
