Here${\mathrm{H}}_2\mathrm{S}{\mathrm{O}}_4$has maximum number of oxo groups that is two.

$\mathrm{M}=\mathrm{O}$bonds are called oxo bonds in inorganic compounds.${\mathrm{H}}_2\mathrm{S}{\mathrm{O}}_4$has two$\mathrm{S}=\mathrm{O}$bonds; whereas${\mathrm{H}}_2\mathrm{S}{\mathrm{O}}_3$has one$\mathrm{S}=\mathrm{O}$bond,${\mathrm{H}}_3\mathrm{P}{\mathrm{O}}_3$has one$\mathrm{P}=\mathrm{O}$and${\mathrm{H}}_3\mathrm{P}{\mathrm{O}}_4$also has one$\mathrm{P}=\mathrm{O}$bond.
