Question # 1
Why the lattice energy of Fluorides is greater than Chlorides?
- Ans 1: Due to small size of fluoride ions(f),there will be a better overlap of orbitals and consequently leads to shorter and stronger bonds with other elements.Ionic fluorides have higher lattice energies than the chlorides and the value is responsible for the insolubility of the fluorides in water.Due to low dissociation energy of fluorine molecule,it is highly reactive.The other halogens react slowly under similar conditions.The fluorides are,however more stable with respect to dissociation into elements.
