• # question_answer Which of the following represents the correct order of decreasing number of $S=O$bonds? 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) ${{H}_{2}}S{{O}_{3}}>{{H}_{2}}{{S}_{2}}{{O}_{8}}>{{H}_{2}}S{{O}_{4}}$

 The structures of are as follows: Thus, the correct order of decreasing number of $S=O$bonds is ${{H}_{2}}{{S}_{2}}{{O}_{8}}>{{H}_{2}}S{{O}_{4}}>{{H}_{2}}S{{O}_{3}}$
