Hydrogen bonding do not exist in the molecule of:
Correct answer: A. Hydrogen gas (H2)
- A. Hydrogen gas (H2)
- B. Proteins
- C. Carbohydrates
- D. Ammonia (NH3)
Explanation
Hydrogen bonding is an intermolecular force that occurs when a hydrogen atom is covalently bonded to a highly electronegative atom, such as nitrogen, oxygen, or fluorine. This interaction is absent in hydrogen gas (H2) because it consists of two hydrogen atoms bonded together, without the presence of any electronegative atoms. In contrast, proteins, carbohydrates, and ammonia all have structures that allow for hydrogen bonding due to the presence of nitrogen, oxygen, or hydroxyl groups.

About Hydrogen Bonding
Hydrogen bonding is the strong attraction between hydrogen attached to nitrogen, oxygen or fluorine and an electronegative atom in the same or another molecule. It explains unusual boiling points, viscosity, surface tension, water's properties and the difference between intermolecular and intramolecular hydrogen bonding.
