NEET (UG) 2023 — Question 78

Match List - I with List- II : List - I

List - I (Oxoacids of Sulphur)	List - II (Bonds)
A. Peroxodisulphuric acid	I. Two $\mathrm{S}-\mathrm{OH}$ ,Four $\mathrm{S}=\mathrm{O}$ , One S-O-S
B. Sulphuric acid	II. Two S-OH, One $\mathrm{S}=\mathrm{O}$
C. Pyrosulphuric acid	III. Two S-OH,Four S=O, One S-O-O-S
D. Sulphurous acid	IV. Two S-OH, Two $\mathrm{S}=\mathrm{O}$

Choose the correct answer from the options given below :

Option A:
A-III, B-IV, C-I, D-II
Correct
Option B:
A-I, B-III, C-IV, D-II
Option C:
A-III, B-IV, C-II, D-I
Option D:
A-I, B-III, C-II, D-IV

Answer: A

Step-by-step solution

Peroxodisulphuric acid has two S-OH, four S=O, and one S-O-O-S bond (A-III). Sulphuric acid has two S-OH and two S=O bonds (B-IV). Pyrosulphuric acid has two S-OH, four S=O, and one S-O-S bond (C-I). Sulphurous acid has two S-OH and one S=O bond (D-II). Thus the correct matching is A-III, B-IV, C-I, D-II, which corresponds to option A.
