A carbon–carbon bond is a covalent bond between two carbon atoms. The most common form is the single bond: a bond composed of two electrons, one from each of the two atoms. The carbon–carbon single bond is a sigma bond and is formed between one hybridized orbital from each of the carbon atoms. In ethane, the orbitals are sp -hybridized orbitals, but single bonds formed between carbon atoms with other hybridizations do occur (e.g. sp to sp ). In fact, the car… WebA C=C bond is about 1.5 times as strong as a C=C bond. That would make it vibrate faster than a C-H bond. But µ (C-C) = 6, while µ (C-H) = 0.92. The reduced mass of a C-C pair is about 6.5 times that of a C-H pair. The greater reduced mass makes the C=C bond vibrate much more slowly than a C-H bond.
