A) \[Ba{{(OH)}_{2}}<Ca{{(OH)}_{2}}<Sr{{(OH)}_{2}}<Mg{{(OH)}_{2}}\]
B) \[Mg{{(OH)}_{2}}<Sr{{(OH)}_{2}}<Ca{{(OH)}_{2}}<Ba{{(OH)}_{2}}\]
C) \[Mg{{(OH)}_{2}}<Ca{{(OH)}_{2}}<Sr{{(OH)}_{2}}<Ba{{(OH)}_{2}}\]
D) \[Ba{{(OH)}_{2}}<Sr{{(OH)}_{2}}<Ca{{(OH)}_{2}}<Mg{{(OH)}_{2}}\]
Correct Answer: D
Solution :
[d] Stability of ionic compounds decreases with decrease in lattice enthalpy. Thus stability of alkaline earth metal hydroxide- decreases with decrease in lattice enthalpy as the size of alkali earth metal cations increases down the group.You need to login to perform this action.
