Question
Explain the reducing character of hydrogen halides.
✓

Answer

  • The reducing character of hydrogen halides increases from HF to HI.
  • HF does not show any reducing property while HI is a strong reducing agent.
  • H-X bond strength and thermal stability of hydrogen halides decrease from HF to HI.
Unlike other hydrogen halides, HF does not dissociate releasing hydrogen, hence HF is not a reducing agent.
