$MgCl_2$

Vedclass · Answer

(B) The hydration energy of alkaline earth metal ions decreases as the size of the ion increases $(Mg^{2+} > Ca^{2+} > Sr^{2+} > Ba^{2+})$. $MgCl_2$ forms a hexahydrate $(MgCl_2 \cdot 6H_2O)$,whereas $CaCl_2$ forms a hexahydrate,$SrCl_2$ forms a hexahydrate,and $BaCl_2$ forms a dihydrate $(BaCl_2 \cdot 2H_2O)$. Among the given options,$MgCl_2$ has the highest tendency to coordinate water molecules due to its small ionic radius and high charge density,allowing it to form stable hexahydrates.

Column $(A)$	Column $(B)$
$(a)$ $BeO$	$(p)$ Amphoteric
$(b)$ $MgCO_3 \cdot CaCO_3$	$(q)$ Dolomite
$(c)$ $BeCl_2$	$(r)$ Covalent
$(d)$ $Al(OH)_3$	$(s)$ Basic
