The correct order of acid strength is (a) HClO4 < HClO3 < HClO2 < HClO (b) HCIO < HClO2 < HClO3 < HClO4 (c) HClO4 < HClO < HClO2 < HClO3 (d) HClO2 < HClO3 < HClO4 < HClO |

Answer» wer is option (b)(b) HCIO < HClO2 < HClO3 < HClO4Important point to remember,The acidity is based on the OXIDATION states of the compound Higher the oxidation state MEANS more acidic in natureHere we have HCIO, HClO2, HClO3, HClO4The oxidation state of,HClO is +1HClO is +1HClO2 is +3HClO is +1HClO2 is +3HClO3 is +5HClO is +1HClO2 is +3HClO3 is +5HClO4 is +7Since, higher oxidation state AMONG the following is HCLO4 with +5 oxidation state Therefore HClO4 is most acidic {With this information itself we can conclude option (b) is correct because only one option i.e., option (b) has HClO4 with highest acidic strength}Similarly +5 > +3 > +1 in oxidation state,Acidic strength is also in same orderTherefore,HCIO < HClO2 < HClO3 < HClO4Option (b) is correct |
