  3. Hydrogen Bonds aren't technically bonds. there is no sharing of...the partial negative charge on the oxygen, nitrogen or fluorine atom of a different molecule. hydrogen bonding is the reason for water's relatively high boiling point...

  5. A hydrogen bond is specific dipole-dipole bond that occurs between an electronegative atom... to another electronegative atom. This type of bond always includes a hydrogen atom, hence the name. Most hydrogen bonds are stronger...
