A bond is not formed:
Correct answer: D. When repulsive forces exceed attractive forces
- A. When both attractive and repulsive forces are balanced
- B. When attractive forces overcome repulsive forces
- C. When repulsive forces are negligible
- D. When repulsive forces exceed attractive forces
Explanation
Explanation:Bond is formed when either the attraction and repulsion are equal or the force of attraction is greater than repulsion. As a result, the bond is not formed when the repulsion is greater than attraction. Bond is formed when both forces become equal to each other. Bond is also formed when attraction forces dominate repulsive forces. Bond is also formed when repulsive forces becomes equal to zero.

About Bond Energy
Bond energy is the energy needed to break one mole of a particular covalent bond in gaseous molecules, while bond formation releases energy. Reaction enthalpy is estimated by subtracting the total energy of bonds formed from bonds broken, with attention to average bond energies and their limitations for specific molecules.
