Statement I: Chlorides of both beryllium and aluminium have CI bridged

1.	Statement I: Chlorides of both beryllium and aluminium have CI bridged chloride structure in vapour phase and both are lewis bases.Statement II: Beryllium and aluminium hydroxides dissolve in excess of alkali to give beryllate and aluminate ions.(1) Both Statement I & Statement II are true(2) Statement I is true & Statement II is false(3) Statement I is false & Statement II is true(4) Both Statement I& Statement II are false
Answer» Correct option is (3) Statement I is false & Statement II is true The chlorides of both beryllium and aluminium have Cl^- bridged chloride structure in vapour phase. Both the chlorides are soluble in organic solvents and are strong Lewis acids. Beryllium hydroxide dissolves in excess of alkali to give a beryllate ion, [Be(OH)₄]^2- just as aluminium hydroxide gives aluminate ion, [Al(OH)₄]^-.

Answer»

Correct option is (3) Statement I is false & Statement II is true

The chlorides of both beryllium and aluminium have Cl^- bridged chloride structure in vapour phase. Both the chlorides are soluble in organic solvents and are strong Lewis acids.

Beryllium hydroxide dissolves in excess of alkali to give a beryllate ion, [Be(OH)₄]^2- just as aluminium hydroxide gives aluminate ion, [Al(OH)₄]^-.
