Which has the stronger intramolecular forces N2 or H2O? Explain both your answers.

Answer 1

Not sure if you meant intramolecular or intermolecular force, but since you wrote intramolecular, the answer would be the intramolecular forces in H₂O are stronger than the one in N₂. The bond energy holding H and O together is about 3 or 4 times more than that holding two nitrogen atoms together. If you meant to ask about intermolecular forces, the answer is the same in that the intermolecular forces in H₂O are much stronger than those in N₂. In H₂O, the intermolecular forces are not only hydrogen bonging, but you also have dipole-dipole and dispersion forces. In N₂, you have only dispersion forces.
