Question

the boiling point of nh3 h2o &hf are exceptional heihher explain

Answer 1

Due to the higher partial charges on H and F in HF, a hydrogen bond between HF molecules is stronger than that between NH3 molecules. The higher boiling point of HF is thus due to stronger H-bonds. Explain whythe boiling point of water (100 °C) ishigher than both HF and NH3.

PLEASE MAKE AS BRAIN LIST

Answer 2

The boiling points of NH₃, H₂O, and HF are exceptionally higher because of hydrogen bonding.

• The hydrides of N, O, and F have exceptionally higher boiling points than the rest of the hydrides of Group 15, 16, and 17 respectively.
• Nitrogen, oxygen, and fluorine have very high electronegativities as compared to the rest of the members.
• This high electronegativity is the reason that these elements can form hydrogen bonds with H atoms.
• The intermolecular hydrogen bonding in Ammonia, Water, and Hydrogen Fluoride results in their exceptionally high boiling points.
