Expert Answer:

  • Fluorine usually shows a negative oxidation state of -1 except in HOF where it shows an oxidation state of +1.
  • The other halogens in addition to a negative oxidation state of -1 and positive oxidation state of +1 also show higher positive oxidation states of +3, +5 and +7.
  • In principle, F should not show positive oxidation states since it is the most electronegative element known.
  • In spite of this, F shows an oxidation state of +1 in highly stable HOF molecule.
