What products are expected from the disproportionation reaction of hypochlorous acid ($\text{HOCl}$)?

The decreasing values of bond angles from ${\text{NH}}_3$ ($106^{\circ }$) to ${\text{SbH}}_3$ ($101^{\circ }$) down group-15 of the periodic table is due to:

Which one of the following is the correct statement?

The bond dissociation energy of $\text{B}-\text{F}$ in ${\text{BF}}_3$ is $646{\text{kJ mol}}^{-1}$ whereas that of $\text{C}-\text{F}$ in ${\text{CF}}_4$ is $515{\text{kJ mol}}^{-1}$. The correct reason for higher $\text{B}-\text{F}$ bond dissociation energy as compared to that of $\text{C}-\text{F}$ is:
