Problem 4 : Explain the formation of a coordinate covalent bond in the ammonia (NH₃) molecule.
Solution :
In the ammonia (NH₃) molecule, a coordinate covalent bond is formed between the lone pair of electrons on the nitrogen (N) atom and an empty orbital on a proton (H⁺) from another molecule. This results in the formation of an ammonium ion (NH₄⁺):
NH₃ + H⁺ → NH₄⁺
The lone pair of electrons on the nitrogen atom is donated to the hydrogen ion, creating a shared pair of electrons between nitrogen and hydrogen. This type of bond is called a coordinate covalent bond because both electrons in the bond come from the nitrogen atom.
