Question

Consider the oxy acid $HCl{O}_n$ series, here value of $n$ is 1 to 4, then incorrect statement regarding these oxy acids is:

• A. Acidic character of oxy acids increase with in increasing value of $n$
• B. Oxidising power of oxy acids increases with decreasing value of $n$
• C. Thermal stability of oxy acids decreases with increasing value of $n$
• D. $Cl-O$ bond order decreases with decreasing value of $n$

Answer 1

The correct option is C Thermal stability of oxy acids decreases with increasing value of $n$

Acidic character: $HOCl<HCl{O}_2<HCl{O}_3<HCl{O}_4$
Oxidising power: $HOCl>HCl{O}_2>HCl{O}_3>HCl{O}_4$
Thermal stability: $HOCl<HCl{O}_2<HCl{O}_3<HCl{O}_4$
$Cl-O$ bond order: $HOCl<HCl{O}_2<HCl{O}_3<HCl{O}_4$
