What molecules can form hydrogen bonds?
Understand the Problem
The question is asking about the types of molecules that are capable of forming hydrogen bonds. Hydrogen bonds typically occur in molecules where hydrogen is directly bonded to highly electronegative atoms such as nitrogen, oxygen, or fluorine.
Answer
Molecules with H bonded to F, O, or N.
The final answer is molecules containing hydrogen atoms covalently bonded to fluorine, oxygen, or nitrogen.
Answer for screen readers
The final answer is molecules containing hydrogen atoms covalently bonded to fluorine, oxygen, or nitrogen.
More Information
Hydrogen bonding is a type of intermolecular force that occurs when hydrogen is bonded to highly electronegative atoms such as fluorine, oxygen, or nitrogen. Common examples include water (H₂O), ammonia (NH₃), and hydrogen fluoride (HF).
Tips
A common mistake is thinking that hydrogen bonds can form with any electronegative atom. It's crucial that the atom is specifically fluorine, oxygen, or nitrogen due to their high electronegativity.
