Lattice enthalpy of an ionic compound depends upon

Answer»

Charge on the ion only
Size of the ion only
Packing of ions only
Charge on the ion and size of the ion.

Solution :`SF_(4)` (`SP^(3)d`hybridisation)has see SAW geometry with 1 LONE pair`CF_(4)`(`sp^(3)` hybridisation) has TETRAHEDRAL geometry with 0 lone pair
`XeF_(4)`(`sp^(3)d^(2)`hybridisation) has octahedral shape with 2 lone pairs.
