Chemistry Question on Group 17 Elements

The correct order of acidity of oxoacids of halogens is

A

HClO<HClO2<HClO3<HClO4HClO < HClO_2 < HClO_3 < HClO_4

B

HClO4<HClO3<HClO2<HClOHClO_4 < HClO_3 < HClO_2 < HClO

C

HClO<HClO4<HClO3<HClO2HClO < HClO_4 < HClO_3 < HClO_2

D

HClO4<HClO2<HClO3<HClOHClO_4 < HClO_2 < HClO_3 < HClO

Answer

HClO<HClO2<HClO3<HClO4HClO < HClO_2 < HClO_3 < HClO_4

Explanation

Solution

Acidic strength of oxoacids of a particular halogen atom increases with increase in oxidation number thus the order of acidic strength is $\overset{+1}{HClO}
