Question

Beryllium exhibits some similarities with aluminium. Point out three such properties.

Answer 1

i) The radius ratio of ${ Be }^{ 2+ }$ is same to that of ${ Al }^{ 3+ }$, hence they both exhibit some similarities in their properties

ii) Due to the presence of oxide film, they both remain unaffected by the acid attack

iii) Hydroxides of both beryllium and aluminium dissolves in excess of alkali

iv) Chlorides of both beryllium and aluminium acts as Lewis acid and both of their chloride salts dissolves in organic solvents

v) The ions of both beryllium and aluminium have tendency to form complexes.
