What is bond order?

Can anyone define bond order comprehensively?

The bond order is the number of bonding pairs of electrons between two atoms. For example a a single bond between two C has a bond order of 1, while a double bond between two C has a bond order of two. Similarly, N2 which is a triple bond between two nitrogens has a bond order of 3. If the bond order is 0 the molecule does not form. Molecules that have resonance can have bond orders that are not whole numbers.

Bond order is defined by the number of chemical bonds between a pair of atoms and indicates the stability of a bond. In a covalent bond between two atoms, a single bond has a bond order of one, a double bond has a bond order of two, and so on. Bond order and length are inversely proportional. When bond order increases, the bond length decreases.

Bond order is just the number of bonds present between atoms. So if you had a single bond between two atoms, the bond order would be 1. If you had a double bond between two atoms, the bond order would be 2, so on and so forth

It's basically the number of present bonds between atoms. One bond equates to a bond order of one, a double bond equates to a bond order of two, and a triple bond between two atoms equates to a bond order of three.

Just checking my understanding: bond order refers only to the number of bonds present and not to any actual chronological order or bonds (sounds silly, but that's what I originally inferred from the use of the word order haha). A single bond has a bond order of one, a double bond has a bond order of two, and a triple bond has a bond order of three. Bond order and length are inversely proportional.

As others have said above, bond order is the number of bonds present between 2 atoms. If there is a single bond between 2 atoms, the bond order is 1. If there is a double bond between 2 atoms, the bond order is 2. If there is a triple bond between 2 atoms, the bond order is 3.

Bond order is simply the number of covalent bonds that is shared within two atoms. For example, when the atoms share one pair of electrons, they have a single bond, therefore a bond order of 1. A bond order of 2 has two electrons pairs, while sharing three electron pairs results in having a bond order of 3.

Yes, this is correct. I was confused about this concept too, but this thread really helped and you summarized it well.
