Explain the relationship of bond length and bond strength

Answer 1

General answer:

Single bond: weakest bond, longest distance apart

Double bond: medium bond strength, medium distance apart (in the middle between single and triple)

Triple bond: strongest bond strength, shortest distance apart

Closer together = stronger bond strength, takes more energy to break apart

Farther apart = weaker bond strength, takes less energy to break apart

Answer 2

The longer the bond length, the grater the distance between the two nuclei of the atoms in the bond. From Coulomb's law, the strength of a bond is inversely proportional to its length. The shorter the bond length, the better the two nuclei overlap and the stronger the bond.
