cc bond length
Bond lengths in organic compounds. The carbon–carbon (C–C) bond length in diamond is 154 pm, which 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.
Bond Length. Bond length is defined as the distance between the centers of two covalently bonded atoms. The length of the bond is determined by the number of bonded electrons (the bond order). The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length.

Periodic Trends. Atoms with multiple bonds between them have shorter bond lengths than singly bonded ones; this is a major criterion for experimentally determining the multiplicity of a bond. For example, the bond length of [latex]C – C [/latex] is 154 pm; the bond length of [latex]C = C [/latex] is 133 pm; and finally,
2 Answers. You can draw Hyper conjugating Structures to compare bond length. More the α Hydrogen of alkene, more are the Hyper conjugating structures, more is the delocalization of π-bond and more is the bond length (since double bond character decreases, bond length increases). Thus bond length C would be greater than A. As there are 4 α

Research conducted with X-rays has allowed us to determine that the bond length for all six C-C bonds in benzene is 142 pm.. It is perhaps unfortunate that many of us still draw a benzene molecule with three double bonds and three single bonds, inviting the false assumption that three C-C bonds in benzene have a bond length of 134 pm and the other three of 154 pm.
This bond is a covalent bond meaning that carbon shares its outer valence electrons with up to four hydrogens. This completes both of their outer shells making them stable. 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 and therefore CH bond much stronger than CC bond.
C-C Bond Distances. Frame 10. This slide shows the different types of C-C bonds. Of the bonds that are sp 3-sp 3, the more R groups on each carbon, the more crowded the area is with the larger carbon atoms, and the more the measured bond stretches away to compensate for the repulsion.So, for the first three bond types on the slide, with each H that is replaced by an R group, the bond length
Periodic Trends. Atoms with multiple bonds between them have shorter bond lengths than singly bonded ones; this is a major criterion for experimentally determining the multiplicity of a bond. For example, the bond length of C−C is 154 pm; the bond length of C=C is 133 pm; and finally, the bond length of C≡C is 120 pm.
C) C-C bond lengths are slightly different for different molecules, but are usually similar to the corresponding average values for C-C single, double, triple, and aromatic bond lengths. The most significant differences are for molecules that contain conjugated π bonds.
