It is generally considered the average length for a carbon–carbon single bond, but is also the largest bond length that exists for ordinary carbon covalent bonds. Since one atomic unit of length (i.e., a Bohr radius) is 52.9177 pm, the C–C bond length is 2.91 atomic units, or approximately three Bohr radii long.

In this case, the average bond length is a common way of expressing the distance between its atoms. [citation needed] ... Diamond's C-C bond has a distance of ...
The average length of a C–C single bond is 154 pm; that of a C=C double bond is 133 pm. In localized cyclohexatriene, the carbon–carbon bonds should be alternating 154 and 133 pm. Instead, all carbon–carbon bonds in benzene are found to be about 139 pm, a bond length intermediate between single and double bond.
Molecular geometries can be specified in terms of 'bond lengths', 'bond angles' and 'torsional angles'. The bond length is defined to be the average distance between the nuclei of two atoms bonded together in any given molecule. A bond angle is the angle formed between three atoms across at least two bonds.

Carbon–hydrogen bonds have a bond length of about 1.09 Å (1.09 × 10 −10 m) and a bond energy of about 413 kJ/mol (see table below). Using Pauling's scale —C (2.55) and H (2.2)—the electronegativity difference between these two atoms is 0.35.
The structure of carbodicarbenes greatly resembles that of carbodiphosphoranes. [4] Computational data for a N-methyl-substituted carbodicarbene predicted a carbon-carbon bond with a length only marginally longer than a C=C bond in a typical allene at 1.358 Å (compared with 1.308 Å for allene), but with a significantly bent bond angle of 131.8° (compared to 180° for a standard linear ...
