Question

The correct order of thermal stability of hydroxides is :

Options

A.Ba(OH)2 < Ca(OH)2 < Sr(OH)2 < Mg(OH)2
B.Ba(OH)2 < Sr(OH)2 < Ca(OH)2 < Mg(OH)2
C.Mg(OH)2 < Ca(OH)2 < Sr(OH)2 < Ba(OH)2
D.Mg(OH)2 < Sr(OH)2 < Ca(OH)2 < Ba(OH)2

Solution

Larger cation is able to stabilize polyatomic anion more than smaller cation.
