Why are ionic bonds stronger than hydrogen bonds?

Because Ionic bonds are complete giving of one electron to another due to a high electonegative difference, while hydrogen bonding is the slight positive and negative sides of a molecule allowing two molecules to interact. The former is a stronger interaction.

Additionally, ionic bonds are intramolecular while hydrogen bonds are intermolecular. And intramolecular bonds are always stronger than hydrogen bonds.

I think it's because the electrostatic forces hold ionic bonds together tightly and because they are between metal and nonmetal, while hydrogen bonds consist of hydrogen and an element of a higher electronegativity. Ionic bonds are when electrons are transferred from one element to the other. Hydrogen bonds create partial charges.

An ionic bond is considered intramolecular within a molecule and intermolecular within an ionic solid. Since the metal completely gives one or more electrons to the nonmetal, the bond is much stronger than a H bond which is completely intermolecular and is only caused by the attraction of positive and negative dipoles.

Ionic bonds are stronger since they are the electrostatic force of attraction between positively and negatively charged ions. Hydrogen bonds are weaker since they are between dipoles (partially charged regions of a molecule).
