The ionic radii (VI coordination) increases from $\ce{Zn^2+}(\pu{0.74 Å)}$ to $\ce{Cd^2+}(\pu{0.95 Å)}$ to $\ce{Hg^2+}(\pu{1.02Å)}$. Applying Fajans' rule, the expected order of covalent character:
$$\ce{ZnCl2} > \ce{CdCl2} > \ce{HgCl2}$$
But consider the following properties:
Water solubility order (per $\pu{100 g}$ at $\pu{20 °C})$:
$$\ce{ZnCl2}~(\...

Consider the figure given in the previous answer:
Due to a lone pair of $\ce{e-}$ and thus, due to lp-bp repulsions, all equatorial fluorine atoms will move upwards but still remain in a plane. Now, the $\ce{Br}$ will be out of that plane. This will cause the $\ce{F_{axial}-Br-F_{equatorial}}$ angle to reduce. I think $\ce{F_{equatorial}-Br-F_{equatorial}}$ ...
