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
Correct Answer:
B
Solution :
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
