Question

Arrange the following compounds on the
basis of lattice energies in decreasing
(descending) order: BeF2, AICI3, LiCl
CaCl2, NaCl.
​

Answer 1

Answer:

AlCl_{3} has the highest lattice energy.

Explanation:

The correct order of lattice energies in decreasing order :

AlCl_{3} , BeF_{2}, CaCl_{2}, LiCL , NaCl

The energy used to break an ionic solid and convert it into its gaseous icon is known as LATTICE ENERGY .

LATTICE ENERGY is also known as known as energy released when gaseous ions combine to form ionic solid.
