Hydrogen bonds are not covalent bonds and do not share electrons. Instead, they are a type of intermolecular attraction that occurs when a hydrogen atom covalently bonded to a highly electronegative atom (like nitrogen, oxygen, or fluorine) is attracted to another electronegative atom.
Based on your options:
- Hydrogen bonds are covalent bonds. - False
- Hydrogen bonds can form between H and N. - True
- Hydrogen bonds occur within a water molecule. - False (They occur between water molecules, not within a single water molecule.)
- Hydrogen bonds share electrons between the two bonded atoms. - False
Therefore, the correct answer is: can form between H and N.
