Diagonal Relationship Of Beryllium and Aluminium

Beryllium shows resemblance with its diagonally opposite element aluminium.

Points of similarity are:

1) Both metals have a tendency to form covalent compounds e.g. the chlorides of both being covalent are soluble in organic solvents.

Both metals have the tendency to form covalent compounds.

2) BeCl2 and AlCl3 act as lewis acids and use in friedal crafts catalyst.

3) Both metals dissolves in alkalies to form soluble complexes beryllates and aluminates.

4) The oxides of both are hard, high melting insoluble solids.

5) The oxides and hydroxides of both are amphoteric inn nature.

6) Carbides of both the metals react with water Liberating methane gas.
