1) Both metals have a tendency to form covalent compounds e.g. the chlorides of both being covalent are soluble in organic solvents.
2) Both BeCl2 and AlCl3 act as a Lewis acids and are used as Friedel – Crafts catalyst.
3) These two elements have same electronegativity and the polarising power i.e. charge/ radius ratio of their ions are very similar.
4) BothBeCl2 and AlCl3 have chlorine bridged structures in the vapour phase.
