A) \[{{H}_{2}}S{{O}_{4}}>{{H}_{2}}S{{O}_{3}}>{{H}_{2}}{{S}_{2}}{{O}_{8}}\]
B) \[{{H}_{2}}{{S}_{2}}{{O}_{8}}>{{H}_{2}}S{{O}_{3}}>{{H}_{2}}S{{O}_{4}}\]
C) \[{{H}_{2}}{{S}_{2}}{{O}_{8}}>{{H}_{2}}S{{O}_{4}}>{{H}_{2}}S{{O}_{3}}\]
D) \[{{H}_{2}}S{{O}_{3}}>{{H}_{2}}{{S}_{2}}{{O}_{8}}>{{H}_{2}}S{{O}_{4}}\]
Correct Answer: C
Solution :
The structures of are as follows: |
Thus, the correct order of decreasing number of \[S=O\]bonds is |
\[{{H}_{2}}{{S}_{2}}{{O}_{8}}>{{H}_{2}}S{{O}_{4}}>{{H}_{2}}S{{O}_{3}}\] |
