Both form basic oxides and hydroxides

Vedclass · Answer

(A) The oxides and hydroxides of both $Be$ and $Al$ are amphoteric in nature,not basic.Both $Be$ and $Al$ exhibit diagonal relationship due to similar ionic potential ($charge/size$ ratio).$Be$ and $Al$ both form complexes (e.g.,$[BeF_4]^{2-}$ and $[AlF_6]^{3-}$).Their chlorides ($BeCl_2$ and $Al_2Cl_6$) exist as bridged structures in the vapour phase and are covalent,making them soluble in organic solvents.Therefore,the statement that they form basic oxides and hydroxides is incorrect as they are amphoteric.

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