    Which among the following is strongest acid?

    A) \[H(ClO){{O}_{2}}\]        

    B) \[H(ClO){{O}_{3}}\]

    C)  \[H(ClO)O\]     

    D)  \[H(ClO)\]

    Correct Answer: B

    Solution :

                     \[Acidic\text{ }strength\text{ }of\text{ }acid\propto oxidation\text{ }number\] \[\therefore \] \[\overset{+1}{\mathop{HClO}}\,<\overset{+3}{\mathop{HCl{{O}_{2}}}}\,<\overset{+5}{\mathop{HCl{{O}_{3}}}}\,<\overset{+7}{\mathop{HCl{{O}_{4}}}}\,\] \[\therefore \]\[H(ClO){{O}_{3}}\]is the strongest acid
