The correct order of increasing thermal stability of K_(2)CO_(3) , MgC

1.	The correct order of increasing thermal stability of K_(2)CO_(3) , MgCO_(3) , CaCO_(3)and BeCO_(3) is
Answer» `K_(2)CO_(3) lt MgCO_(3) lt CaCO_(3) lt BeCO_(3)` `BeCO_(3) lt MgCO_(3) lt K_(2)CO_(3) lt CaCO_(3)` `BeCO_(3) lt MgCO_(3) lt CaCO_(3) lt K_(2)CO_(3)` `MgCO_(3) lt BeCO_(3) lt CaCO_(3) lt K_(2)CO_(3)` Solution :Stability increases as the basic character of the corresponding HYDROXIDE increases , i.e., option (C) is correct .
