Question

Which of the following increasing order is not correct as mentioned in the property with it?

• A. $HClO$ < $HCl{O}_2$ < $HCl{O}_3$ < $HCl{O}_4$ (thermal stability)
• B. $HCl{O}_4$ < $HCl{O}_3$ < $HCl{O}_2$ < $HClO$ (oxidising power)
• C. $F^{-}<C{l}^{-}<B{r}^{-}<I^{-}$ (reducing nature)
• D. $HI{O}_4$ < $ICl$ < $I_2$ < $HI$ (oxidation number of iodine)

Answer 1

The correct option is D $HI{O}_4$ < $ICl$ < $I_2$ < $HI$ (oxidation number of iodine)

$HI{O}_4⟶1+x-8=0$

$\Rightarrow x=+7$

$ICl⟶x-1=0$

$\Rightarrow x=+1$

$I_2⟶x=0$ $x$=oxidation number of iodine

$HI⟶$ $x=-1$

so, order will be $HI<I_2<ICl<HI{O}_4$
