Question

Why are shorter bonds stronger?

Answer 1

1. Bond length is the shortest possible distance present between the two atoms bonded together.
2. The bond energy is dependent on the strength of the bond. If the bond is strong then a high amount of energy is needed to break the bond.
3. Similarly, if the bond is weak then low energy is needed.
4. If in the molecule the closeness in the atom increases, the bond becomes more tightly packed, so it requires higher energy to break the bonds.
5. The number of electrons increases the bond strength which will decrease the gap between the two atoms.
6. If in case a sigma bond is present between two atoms then such bond is longer and weaker compared with pi bonds in similar atoms.
7. Thus shorter is the bond length stronger is the bond because this requires higher energy to break such bonds.
