A Relation Between Bond Order and Covalent Bond Distance

A relation between covalent bond distance and bond order of the form R=R1[2/3+1/3×(n−1/n+1)p/2] is proposed and tested against the available experimental data. A suitable expression for all covalent bond distances between atoms of the first row of the periodic table of the form R=Z−A/Z−B[2/3+1/3(1/3)p/2] is also proposed. The agreement between calculated and observed values is well within the limits of the experimental errors.
