Here's a breakdown:
* The bond holding hydrogen to oxygen in a water molecule is a covalent bond. This is a strong bond formed by the sharing of electrons between the hydrogen and oxygen atoms.
* Hydrogen bonds are intermolecular bonds. This means they occur between different molecules, not within the same molecule. They form due to the attraction between a slightly positive hydrogen atom in one molecule and a slightly negative oxygen atom in another molecule.
In summary:
* Covalent bonds (within the water molecule) are stronger than hydrogen bonds (between water molecules).
This difference in strength is why water molecules are able to form liquid states at relatively high temperatures, even though the individual covalent bonds are quite strong. The hydrogen bonds can break and reform relatively easily, allowing the water molecules to move around freely.
