Igot points just for you if you answer this question

Hydrogen bonds are intermolecular forces , (between molecules) rather than intramolecular (within-molecule) forces. Hydrogen bonds are weaker than chemical bonds. For example, they are much weaker than the covalent bonds holding atoms together within molecules of covalent compounds, so the answer is hydrogen bonds are weaker bonds that form from molecules that have a slight positive charge on one side and a slight negative charge on the other, your welcome hope this is helpful!
