Solution:
Lattice energy Melting point
( L.E.) ( M.P.)
Lattice energy depends on the size of the ion. Smaller the size of anion or cation, higher the value of L.E.
The correct set from the following in which both pairs are in correct order of melting point is :
Lattice energy Melting point
( L.E.) ( M.P.)
Lattice energy depends on the size of the ion. Smaller the size of anion or cation, higher the value of L.E.
