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 hydroxides 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.
