The correct order of the lattice energies of the following ionic compounds is

A

`NaCl gt MgBr_2 gt CaO gt Al_2O_3`

B

`NaCl gt CaO gt Mg Br_2gt Al_2O_3`

C

`Al_2O_3gt MgBr_2 gt CaO gt NaCl`

D

`Al_2O_3 gt CaO gt MgBr_2 gt NaCl`

Text Solution

Verified by Experts

The correct Answer is:
D
Smaller the size of ions and more the charge more is the lattice energy. (More charge density on ions, more lattice energy).
