Match List-I with List-II : List-I (Oxoacids of Sulphur) A. Peroxodisulphuric acid B. Sulphuric acid C. Pyrosulphuric acid D. Sulphurous acid List-II (Bonds) I. Two S-OH, Four S=O, One S-O-S II. Two S-OH, One S=O III. Two S-OH, Four S=O, One S-O-O-S IV. Two S-OH, Two S=O Choose the correct answer from the options given below.
A-I, B-III, C-II, D-IV
A-III, B-IV, C-I, D-II
A-I, B-III, C-IV, D-II
A-III, B-IV, C-II, D-I
Peroxodisulphuric acid () has a peroxide linkage (S-O-O-S), two S-OH, and four S=O bonds (A-III). Sulphuric acid () has two S-OH and two S=O bonds (B-IV). Pyrosulphuric acid () has an S-O-S linkage, two S-OH, and four S=O bonds (C-I). Sulphurous acid () has two S-OH and one S=O bond (D-II). Thus, the correct match is A-III, B-IV, C-I, D-II.
