Question

Hydrogen bonding is even more effective in water, with the boiling point of water very high for the size of its molecule. Explain why water can hydrogen bond more effectively than hydrogen fluoride.

Answer 1

Water can hydrogen bond more effectively than hydrogen fluoride due to the presence of hydrogen bonding in water molecules but not in hydrogen fluoride molecules.

Step-by-step explanation:

Water can hydrogen bond more effectively than hydrogen fluoride because water molecules experience hydrogen bonding, while hydrogen fluoride molecules do not. Hydrogen bonding is a strong form of dipole-dipole interaction that occurs in molecules with an H atom bonded to an N, O, or F atom. The large difference in electronegativity between the hydrogen and oxygen atoms in water leads to a large partial positive charge on the hydrogen atom and a correspondingly large partial negative charge on the oxygen atom. This results in a strong dipole-dipole interaction and the formation of hydrogen bonds.
