On the basis of dipole moments and/or hydrogen bonding, explain in a qualitative way the differences in the boiling points of acetone (56.2 °C) and 1-propanol … WebApr 8, 2024 · The unusually high boiling point of hydrogen fluoride between halogen acids is due to the presence of hydrogen bonding. H₂O is a liquid while H₂S, H₂Se and H₂Te are all standardised gases. In water, hydrogen bonding creates a contact in water molecules which results in the boiling point of water being higher than in other compounds.
WebA water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent. This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons.
