With respect to hypochlorite, chlorate and perchlorate ions, choose the correct Statements (s) 
 

The structure of HClO and  ${\mathrm{HClO}}_4$ are as follows.

The central atom in both HClO and  ${\text{HClO}}_4\mathrm{\hspace{0.17em}}\mathrm{is}\mathrm{\hspace{0.17em}}{\mathrm{sp}}^3$
Reaction of  ${\mathrm{Cl}}_2$ with  ${\mathrm{H}}_2\mathrm{O}$ gives  $\mathrm{HOCl}$ Which decomposed to give reagent oxygen.
 ${\mathrm{Cl}}_2+{\mathrm{H}}_2\mathrm{O}\to [\mathrm{HCl}+\mathrm{HOCl}]\to 2\mathrm{HCl}+\left[\mathrm{O}\right]$
The conjugate base of ${\mathrm{HClO}}_4$ Is a weaker base than  $H_{2}O$
${\mathrm{HClO}}_4$ Is more acidic than $\mathrm{HClO}$  Because of resonance stabilization of its anion.
