What is the correct order of bond dissociation energy for the given halogens?

$SF_{6}$ is known but $SCl_{6}$ is not. Why?

With respect to hypochlorite,chlorate,and perchlorate ions,choose the correct statement$(s)$.
$A.$ The hypochlorite ion is the strongest conjugate base.
$B.$ The molecular shape of only the chlorate ion is influenced by the lone pair of electrons on $Cl$.
$C.$ The hypochlorite and chlorate ions disproportionate to give rise to an identical set of ions.
$D.$ The hypochlorite ion oxidizes the sulfite ion.

When fluoride is heated with conc. $H_2SO_4$ and $MnO_2$,the gas evolved is:

The following order is $NOT$ correct for: $HClO < HClO_2 < HClO_3 < HClO_4$
