White fumes appear around the bottle of anhydrous aluminium chloride. Give reason.
Describe the shapes of $BF_3$ and $BH_4^-$. Assign the hybridisation of boron in these species.
The tendency to form monovalent compounds among the Group $13$ elements is correctly exhibited in :
Choose the correct sequence for the geometry of the given molecules Borazone, Borazole, $B_3O_6^{-3}$ , $Fe_2Cl_6$, trimer of $FCN$. [$'P'$ stands for planar and $'NP'$ stands for non-planar]
Anhydrous $ALCl_3$ is covalent however,when it is dissolved in water hydrared ionic species are formed. This transformation is owing to
