Question

The incorrect statement about the oxoacids, $HClO_{4}$ and $ClO$ , is

• A. The central atom in both $HClO_{4}$ and $HClO$ is $sp^{3}$ hybridized
• B. $HClO_{4}$ is formed in the reaction between $Cl_{2}$ and $H_{2}O$
• C. The conjugate base of $HClO_{4}$ is weaker base than $H_{2}O$
• D. $HClO_{4}$ is more acidic than HClO because of the resonance stabilization of its anion

Answer 1

Answer: (B)

$Cl_{2}+H_{2}O \rightarrow HCl+HOCl$

Acidic: $\underset{a c i d - 1}{H C l O_{4}}>\underset{a c i d - 2}{H_{3} O^{+}}$

Basic: $\underset{C . B . - 1}{ClO_{4}^{-}} < \underset{C . B . - 2}{H_{2} O}$



Resonance stabilization
