Practice Question
Nitrogen gas is an extremely stable molecule because its structure contains which of the following?
Answer Choices:
Correct Answer:
Triple covalent bonds
Rationale:
🔷 Nitrogen gas (N₂) is composed of two nitrogen atoms joined by a triple covalent bond—one of the strongest types of chemical bonds.
🔷 This bond includes one sigma bond and two pi bonds, which require a large amount of energy to break.
🔷 The strength and stability of the triple bond make nitrogen gas chemically inert under normal conditions.
🔷 This is why atmospheric nitrogen must be fixed by certain bacteria or industrial processes before it can be used by most organisms.
