Bond Length Calculator
Estimate covalent bond length using atomic radii and bond order corrections.
Bond Parameters
Estimated Bond Length
1.540 Å
C-C
In Picometers
154.0 pm
In Nanometers
0.1540 nm
Sum of Radii
1.540 Å
Known Value
1.540 Å
Calculation
d = r₁ + r₂ + correction
d = 0.77 + 0.77 + (0.000)
d = 1.540 Å
About Bond Length
Bond length is the equilibrium distance between the nuclei of two bonded atoms. It can be estimated by adding the covalent radii of the atoms involved. Multiple bonds (double, triple) are shorter than single bonds due to increased electron density between the nuclei. Bond length is inversely related to bond strength and bond order.
