Concept: Bond formation is an exothermic process driven by the tendency of atoms to achieve a more stable, lower energy state. This stability is attained when the attractive forces between the atoms outweigh the repulsive forces, leading to a net decrease in potential energy.

Why (C) is correct: For a stable chemical bond to form between two atoms, there must be a net attractive force between them. This attraction leads to a decrease in the potential energy of the system. The most stable state, corresponding to the strongest bond, occurs at the point of maximum attraction and minimum potential energy. This is because energy is released during bond formation, indicating that the bonded state is more stable and has lower potential energy than the separated atoms.

Option Analysis:

• A) Maximum attraction and maximum potential energy: Maximum attraction favors bond formation, but maximum potential energy indicates instability, which is contrary to bond formation.
• B) Minimum attraction and minimum potential energy: Minimum attraction does not favor bond formation. While minimum potential energy is desired, it must be accompanied by significant attraction.
• D) Minimum attraction and maximum potential energy: Both minimum attraction and maximum potential energy are conditions that oppose bond formation.

Correct Answer: (C)
