Vedclass · Answer

(B) Statement $[A]$ is correct: $HClO_4$ is a much stronger acid than $HClO$ because the perchlorate anion $(ClO_4^-)$ is highly resonance-stabilized,whereas the hypochlorite anion $(ClO^-)$ is not.Statement $[B]$ is incorrect: The reaction between $Cl_2$ and $H_2O$ produces $HCl$ and $HOCl$ $(HClO)$,not $HClO_4$.Statement $[C]$ is correct: In $HClO_4$,the central $Cl$ atom is $sp^3$ hybridized ($4$ sigma bonds). In $HClO$,the central $Cl$ atom is also $sp^3$ hybridized ($2$ lone pairs and $2$ sigma bonds).Statement $[D]$ is correct: Since $HClO_4$ is a very strong acid,its conjugate base $ClO_4^-$ is an extremely weak base,much weaker than $H_2O$.
