The correct statements about the oxoacids, HClO 4   and   HClO are,

The correct statements about the oxoacids, HClO4 and HClO are,
  1. the conjugate base of HClO4 is weaker base than H2O.
  2. the central atom in both HClO4 and HClO is  sp3 hybridized.
  3. HClO4 is formed in the reaction between  Cl2 and H2O.
  4. HClO4 is more acidic than HClO because of the resonance stabilization of its anion.

Solution

(i)  HClO4 ⇌H++ClO4- 

ClO4-  is resonance stabilized anion.

HClO ⇌H++ClO- 

∴    HClO4 is more acidic then HClO.

(ii)   Cl2+H2O→HClO+HCl 

(iii)  HClO4 The central atom is sp3 hybridised.

 The central atom is sp3 hybridised.

(iv)  HClO4+H2O→H3O⊕+ClO4- since H2O is accepting H+ from HClO4 so H2O  is stronger base compare to ClO4-.
