Be and Al show similarities in properties due to the diagonal relationship except in the property X given below. What is X ?
Options
- ABoth form basic oxides and hydroxides.
- BIons of both have a strong tendency to form complexes.
- CIn the vapour phase, chlorides of both have Cl - bridged chloride structure.
- DChlorides of both are soluble in organic solvents.
Correct answer
A. Both form basic oxides and hydroxides.
Step-by-step solution
oth metals have the tendency to form covalent compounds BeCl 2   and   AlCl 3 act as lewis acids and use in friedal crafts catalyst Both metals dissolves in alkalies to form soluble complexes beryllates and aluminates The oxides of both are hard, high melting insoluble solids The oxides and hydroxides of both are amphoteric in nature Carbides of both the metals react with water Liberating methane gas Oxides and hydroxides of the given elements are amphoteric in nature. So, Both can not form basic oxide.
