Final answer:
Hydrogen bonds can be found between molecules of ammonia (NH₃) and water (H₂O).
So The correct answer is option a) NH₃ (Ammonia)
Step-by-step explanation:
Hydrogen bonds can be found between molecules of ammonia (NH₃) and water (H₂O). These substances have hydrogen atoms bonded to highly electronegative atoms (nitrogen and oxygen, respectively), creating a polar covalent bond.
The partially positive hydrogen atom in one molecule can form a strong electrostatic attraction with the partially negative nitrogen or oxygen atom in another molecule, resulting in hydrogen bonding.
In chemistry, a hydrogen bond (also known as an H-bond) is a special type of intermolecular force that arises between molecules. It's weaker than a covalent or ionic bond, but stronger than other intermolecular forces like van der Waals forces.
The correct answer is option A) NH₃ (Ammonia)
