Which situation describes a hydrogen bond? View Available Hint (s) Which situation describes a hydrogen bond? The H atom of a water molecule interacts with the O lone-pair electrons of a neighboring water molecule. The H atom of a water molecule covalently bonds to the O in the same molecule. The H bonds to Na in NaH. H + acts as a Lewis acid.

The H atom of a water molecule interacts with the O lone-pair electrons of a neighboring water molecule.

Explanation:

Hydrogen bonding:-

Hydrogen bonding is a special type of the dipole-dipole interaction and it occurs between hydrogen atom that is bonded to highly electronegative atom which is either fluorine, oxygen or nitrogen atom.

Partially positive end of the hydrogen atom is attracted to partially negative end of these atoms which is present in another molecule. It is strong force of attraction between the molecules.

Thus, the answer is: - The H atom of a water molecule interacts with the O lone-pair electrons of a neighboring water molecule.

Answer: Option (a) is the correct answer.

Explanation:

Hydrogen bonding is defined as a bonding which exists between a hydrogen atom and an electronegative atom like O, N and F.

But when H atom of a water molecule covalently bonds to the O in the same molecule then it will be a covalent bond and not a hydrogen bond.

As H atom of a water molecule has a partial positive charge so, it will interact with the O lone-pair electrons of a neighboring water molecule and then it will lead to the formation of a hydrogen bond.

Thus, we can conclude that the situation H atom of a water molecule interacts with the O lone-pair electrons of a neighboring water molecule, describes a hydrogen bond.
