-
Match List-I (Oxoacids of Sulphur) with List-II (Bonds of Sulphur):
Column I
- A. Peroxodisulphuric acid
- B. Sulphuric acid
- C. Pyrosulphuric acid
- D. Sulphurous acid
Column II
- 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
Correct answer: A → III, B → IV, C → I, D → II
Peroxodisulphuric acid has an S–O–O–S link; pyrosulphuric acid has an S–O–S link.
