Identify the correct order of the given compounds against the given property:
Show Hint
Group 2: Basic strength of hydroxides increases down the group.
Updated On: Jun 6, 2026
- $BeCl_2 < MgCl_2 < CaCl_2$ (Covalent character)
- $CaSO_4 < SrSO_4 < BaSO_4$ (Solubility)
- $Mg(OH)_2 < Ca(OH)_2 < Ba(OH)_2$ (Basic character)
- $BaCO_3 < SrCO_3 < MgCO_3$ (Thermal stability)
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Periodic trends in Group 2 compounds.
Step 2: Meaning
Basicity of hydroxides increases down the group.
Step 3: Analysis
Basic character increases from Mg to Ba as solubility/ionic character increases. $Mg(OH)_2 < Ca(OH)_2 < Ba(OH)_2$ is correct.
Step 4: Conclusion
This is the correct trend.
Final Answer: (C)
