(A) Why are fluorides of transition metals more stable in their higher oxidation state as compared to the lower oxidation state? 

 

Answer

  • When transition metals move to higher oxidation states, they donate their electrons and get oxidised. 
  • This results in an ion that is unstable due to its large size.
  • Fluorine is a highly electronegative element. It attracts most of the electron cloud from the elements it is bonding with. 
  • It bonds with electropositive elements and stabilises them by sharing the electron cloud and forming strong covalent bonds .

The ability of fluorine to stabilize the highest oxidation state is attributed to its high lattice energy or high bond enthalpy .
