Question
A nitrogen molecule (N₂) has a strong triple bond. An iodine molecule (I₂) has a weak single bond. Which molecule stores more chemical potential energy, and what is the role of bond length?

Responses
Iodine (I₂) stores more energy because atoms in single bonds are packed more tightly.
Iodine (I₂) stores more energy because atoms in single bonds are packed more tightly.
Iodine (I₂) stores more energy because its longer, weaker bond holds more potential energy.
Iodine (I₂) stores more energy because its longer, weaker bond holds more potential energy.
Nitrogen (N₂) stores more energy because a longer bond is always a much stronger bond.
Nitrogen (N₂) stores more energy because a longer bond is always a much stronger bond.
Nitrogen (N₂) stores more energy because its shorter, stronger bond holds more potential energy.

Nitrogen (N₂) stores more energy because its shorter, stronger bond holds more chemical potential energy.
Explanation: The N≡N triple bond is much stronger (bond dissociation ≈ 940–945 kJ/mol) than the I–I single bond (≈ 150 kJ/mol). Shorter bonds result from greater orbital overlap and are stronger, so more energy is required to break them — i.e., they contain more chemical potential energy.
