Best answer

Answer: 3. A-III, B-IV, C-I, D-II

Key idea: Draw the structure of each oxoacid.

  • A. \(\mathrm{H_2S_2O_8}\), peroxodisulphuric: two S-OH, four S=O and one S-O-O-S: III.
  • B. \(\mathrm{H_2SO_4}\): two S-OH, two S=O: IV.
  • C. \(\mathrm{H_2S_2O_7}\), pyrosulphuric: two S-OH, four S=O, one S-O-S: I.
  • D. \(\mathrm{H_2SO_3}\): two S-OH, one S=O: II.

A-III, B-IV, C-I, D-II: option 3.
