Are found between molecules/compounds and not within molecules/compounds; they are weak bonds that occur between a hydrogen of one molecule being attracted to a more electronegative atom of a second molecule.

Hydrogen bonds are found between molecules/compounds and not within molecules/compounds; they are weak bonds that occur between a hydrogen of one molecule being attracted to a more electronegative atom of a second molecule.

Explanation:

Hydrogen bonds are a kind of dipole-dipole interaction between a hydrogen atom covalently bonded to a very electronegative atom (N, O, or F) that acts as a donor (positively chaged), and another very electronegative atom that works as a receptor (negatively charged).

I hoep you find this information useufl and interesting! Good luck!
