                    The correct order of acid strength is:                                                                                                      

    A)                 \[HClO<HCl{{O}_{2}}<HCl{{O}_{3}}<HCl{{O}_{4}}\]

    B)                         \[HCl{{O}_{4}}<HClO<HCl{{O}_{2}}<HCl{{O}_{3}}\]

    C)                 \[HCl{{O}_{2}}<HCl{{O}_{3}}<HCl{{O}_{4}}<HClO\]

    D)                 \[HCl{{O}_{4}}<HCl{{O}_{3}}<HCl{{O}_{2}}<HClO\]

    Correct Answer: A

    Solution :

                                   Correct order of acid strength \[\underset{+1}{\mathop{HClO}}\,<\underset{+3}{\mathop{HCl{{O}_{2}}}}\,<\underset{+5}{\mathop{HCl{{O}_{3}}}}\,<\underset{+7}{\mathop{HCl{{O}_{4}}}}\,\]                 Acid strength \[\propto \] oxidation number.
