Question

The correct statement(s) about the oxoacids, $HClO_4$ and $HClO$, is(are)

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

Answer 1

Answer: (C)

$HClO _{4}$ is more acidic than $HClO$ because of the resonance stabilization of its anion.

Answer 2

Acidic Nature : $HClO _{4}> HClO$

$H _{2} O + Cl _{2} \rightarrow HCl + HOCl$
