Detailed Solution

The trichlorides of group-l3 elements on hydrolysis form tetrahedral M(OH)4- species; the hybridization state of element M is sp3. Aluminium chloride in acidified aqueous solution forms octahedral AlH2O63+ ion. In this complex ion, the 3d -orbitals of Al are involved and the hybridization state of Al is sp3d2.Boron is unreactive in crystalline form. Aluminium forms a very thin oxide layer on its surface which protects the metal from further attack by oxygen molecules.
