Vedclass · Answer

(A) The structures of the given oxoacids of sulphur are as follows:$1$. Pyrosulphurous acid $(H_2S_2O_5)$: Contains two $S$ atoms with oxidation states $+3$ and $+5$.$2$. Hyposulphurous acid $(H_2S_2O_4)$: Contains two $S$ atoms with oxidation states $+3$ and $+3$.$3$. Pyrosulphuric acid $(H_2S_2O_7)$: Contains two $S$ atoms with oxidation states $+6$ and $+6$.$4$. Peroxodisulphuric acid $(H_2S_2O_8)$: Contains two $S$ atoms with oxidation states $+6$ and $+6$.Thus,pyrosulphurous acid is the only oxoacid among the options where the two sulphur atoms have different oxidation states.

The oxoacid of sulphur which contains two sulphur atoms in different oxidation states is
