The following oxo acids have been arranged in the order decreasing acid strength. ldentify the correct order. `ClOH(I), BrOH(II), IOH(III)`A. `III gt IV gt II gt I`B. `III gt II gt I gt IV`C. `I gt II gt III gt IV`D. `IV gt III gt II gt I` |

Answer» Correct Answer - D The acidity of oxo acid of the same. halogen increases with the increase in oxidation state the halogen. It is because the release of `H^(+)` in each case would result in the formation of `ClO_(4)^(-)` ions. Now as the number of oxygen atoms increases the ion, the more and more dispersal of negative charge occurs, The more and more dispersal of negative charge results in more and more stabilization of the resulting ion. Since a more stable ion would be formed relatively with more ease, therefore, the ease of formation of ions would be `ClO_(4)^(-) gt ClO_(3)^(-) gt ClO_(2)^(-) gt ClO^(-)`. Thus, the acid strength also follow the same trend as given above. |
