Which of the following alkali metal halides has the lowest magnitude of lattice energy?
Options:
Answer:
D
Solution:
Here CsI has the lowest lattice energy.
Lattice energy is directly proportional to the product of charges on the ions and inversely proportional to the interionic distance (which depends on the size of cation and anion). Hence, bigger the sizes of cation and anion, smaller are the lattice energy.
