What contributes to the ability of fluorine to stabilize the highest oxidation state in transition metals?

Options

  1. ALower lattice energy
  2. BLower bond enthalpy terms
  3. CHigher lattice energy
  4. DHigher covalent bond enthalpy terms

Correct answer

C. Higher lattice energy

Step-by-step solution

The paragraph mentions that the ability of fluorine to stabilize the highest oxidation state is due to higher lattice energy in the case of compounds like CoF 3 .
