Of the following compounds, which one is the strongest Bronsted acid in aqueous solution?
Updated On: Jun 18, 2022
- $HClO_3$
- $HClO_2$
- $HOCl$
- $HOBr$
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
$\because$ Higher be the oxidation number of central atom in oxo-acids, more strongly it behave as Bronsted-acid.
Oxidation number for $Cl$ in $HClO _{3} \rightarrow+5$
Oxidation number for $Cl$ in $HClO _{2} \rightarrow+3$
Oxidation number for $Cl$ in $HClO \rightarrow+1$
Oxidation number for $Cl$ in $HBrO \rightarrow+1$
Hence, $HClO _{3}$ is the strongest Bronsted acid in aqueous solution.
Oxidation number for $Cl$ in $HClO _{3} \rightarrow+5$
Oxidation number for $Cl$ in $HClO _{2} \rightarrow+3$
Oxidation number for $Cl$ in $HClO \rightarrow+1$
Oxidation number for $Cl$ in $HBrO \rightarrow+1$
Hence, $HClO _{3}$ is the strongest Bronsted acid in aqueous solution.

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
