When is treated with water, it hydrolysis and forms on whereas in acidified aqueous solution forms ion. Explain what is the hybridisation or boron and aluminium in these species ?
In trivalent state, most of the compounds being covalent are hydrolysed in water, e.g., BC on hydrolysis in water form species, the hybridisation state of B is sp3.
AlCl3 in acidified aqueous solution form octahedral ion. In this complex, the 3d orbitals of Al are involved and the hybridisation state of Al is sp3d2.
