The least stable carbonate of alkali metal is

1.	The least stable carbonate of alkali metal is
Answer» `Cs_(2)CO_(3)` `Na_(2)CO_(3)` `K_(2)CO_(3)` `Rb_(2)CO_(3)` SOLUTION :As the SIZEOF the cation increases , M-O bond weakens and C-O bond STRENGTHENS . Since `Li^(+)` has the smallest size AMONG alkali metals , therefore , Li-O bond is the strongest and C-O bondis the weakest . As a result , `Li_(2)CO_(3)` DECOMPOSERS most readily to give `Li_(2)O` and `CO_(2)`.
