Question
Which pair is not correct order of lattice energy?
The correct answer is:
Smaller size of cation
Larger the size of anion
Larger the charge on cation and anion, larger the polarizing power and thus larger the covalent nature and such compounds have larger lattice energy
charge
size
charge
Thus, 
is less ionic than 
thus lattice energy of is larger than that of
Thus, given order is incorrect
