Lattice energy of an ionic compound depends upon :

Options

  1. ACharge on the ion only
  2. BSize of the ion only
  3. CPacking of ions only
  4. DCharge and size of the ion

Correct answer

D. Charge and size of the ion

Step-by-step solution

L a t t i c e E n e r g y ∝ q 1 q 2 r c + r a Where q represents charge of ion and r represent radius of ion. Lattice energy does not dependent packing of ions.
