BCl3is a monomer that is a gas at room temperature while the analogous Al compound is the Al2Cl2 dimer with 2 chlorides bridging between the two Al's. Draw Lewis structures of each compound and suggest a reason for the significant differences in the strucutres. Note that it is important that Al and B obey the ocetet rule in your Lewis strucutures.
