Question

Discuss bond order and its significance

Answer 1

Answer:

Bond order is the number of chemical bonds between a pair of atoms. For example, in diatomic nitrogen N≡N the bond order is 3. It helps in understanding the strength of bond between two atoms and also the bond length

Bond order = no. Of chemical bonds between 2 atoms

Significance - it helps us to know the strength of bond, and the bond length

Answer 2

Answer:

The bond order of a molecule gives us a measure or index of the strength of the bonds that bind it. The bonds bind the atoms like a rubber band binding your two hands. A double-bond would mean that the rubber band is now folded in half and tied around your hands. Due to the strength of this new double-bond, your hands have moved closer to each other. The molecule is now more stable. Similarly, three bonds or three folds would move your hands even closer. Furthermore, the stronger the bond, the more energy is required to break it — the hands are much easier to free when bound by a single-fold rubber band than a double- or triple-fold band. The energy required to break the bond is referred to as the molecules’ bond energy.
