The decreasing order of hydration enthalpies of earth metal ions is

A

`Be^(2+)gtBa^(2+)gtCa^(2+)gtS^(2+)`

B

`Ba^(2+)gtSr^(2+)gtC_(2)^(2+)gtMg^(2+)gtBe^(2+)`

C

`Be^(2+)gtCa^(2+)gtMg^(2+)gtBa^(2+)`

D

`Be^(2+)gtMg^(2+)gtCa^(2+)gtSr^(2+)gtBa^(2+)`

Text Solution

Verified by Experts

The correct Answer is:
D

Hydration enthalpy decreases as the size increases, `Be^(3+)gtMt^(2+)gtCa^(2+)gtSr^(2+)gtBa^(2+)`
