Vedclass · Answer

(A) $Be$ and $Al$ exhibit a diagonal relationship,leading to many similar properties. Both metals form covalent compounds and their chlorides act as Lewis acids. Both metals dissolve in alkalies to form soluble complexes (beryllates and aluminates). The oxides and hydroxides of both $Be$ and $Al$ are amphoteric in nature,not basic. Therefore,the statement that both form basic oxides and hydroxides is incorrect.

$Be$ and $Al$ show similarities in properties due to the diagonal relationship except in the property $X$ given below. What is $X?$
