Relationship between bond order and bond length?

Can I assume that the longer the bond length, the higher the bond order because bond order corresponds to the number of bonds?

Hi there! Actually, the longer the bond length, the smaller the bond order. A higher bond order corresponds to shorter and stronger bonds. For example, a bond order of 1 corresponds to a single bond, which is a long and weak bond. A bond order of 2 corresponds to a double bond, which is stronger and shorter. So, the longer the bond length, the lower the bond order. Hope that helps!

Not quite, I think you have the relationship reversed. The more bonds you have (single->double->triple) the shorter your bond will be. Same idea with the bond order. If you have a higher BO, you have stronger bond which would be similar to saying there's a shorter bond.
