  • Aug 30, 2018 · AlCl3 is also an electron deficient compound. Since, aluminium has larger size than boron, the back bonding is not possible in AlCl3. Aluminium metal complete its octet by forming coordinate bond with chlorine atom of the other molecule,AlCl3. Thus, coordinate bond forming bridges by chlorine atoms between two Al atoms make a dimer molecule.
  • Reading ModeValence shell electron pair repulsion theory is a simple way of rationalising the shapes of many compounds in which a main group element is surrounded by ligands. ClF3 is a good illustration of this theory. The standard application of VSEPR theory to this molecule is as follows: Central atom: chlorine Valence electrons on central […]

22. Draw the structures of BCl3.NH3 and AlCl3 (dimer). Solution: 23. Explain the nature of boric acid as a Lewis acid in water. Solution: Boric acid is a weak monobasic acid and acts as a Lewis acid by accepting electrons from a hydroxyl ion. B(OH) 3 + 2H 2 O → [B(OH) 4] – + H 3 O + OH- is accepted by the Boric acid and the formation of ...
So, it is interesting to know that both BCl3 & AlCl3 are halides of group 13 elements Electron deficient sp2 hybridised Have empty one p orbital perpendicular to the plane of the molecule. But, former doesn't forms dimer and later forms a dimer, because both the molecules compensate their electron deficiency by different ways.
