Question

Identify the correct sequence of increasing number of a bonds in the structures of the following molecules: I. ${{H}_{2}}{{S}_{2}}{{O}_{6}}$ II. ${{H}_{2}}S{{O}_{3}}$ III. ${{H}_{2}}{{S}_{2}}{{O}_{5}}$

• A. I, II, III
• B. II, III, I
• C. II, I, III
• D. I, III, II

Answer 1

Answer: (B)

II, III, I

Answer 2

Structure of ${{\text{H}}_{\text{2}}}\text{S}{{\text{O}}_{\text{3}}}$ is
So, the correct order of increasing number of bonds is II, III, I
