Correct Answer: Higher the bond energy, shorter the bond length
Solution : The correct option is The higher the bond energy, the shorter the bond length
There is an inverse relationship between bond energy and bond length. Reducing bond length increases bond energy and vice versa. The balance of repulsive and attractive forces in a chemical interaction gives rise to this relationship. When atoms are too far apart, the repulsive forces (originating from electron-electron repulsion and electron-nucleus repulsion) are weaker than the attractive forces.
