(d) describe sp3 hybridisation, as in ethane molecule, sp2 hybridisation, as in ethene and benzene molecules, and sp hybridisation, as in ethyne molecule
(e) explain the shapes of, and bond angles in, the ethane, ethene, benzene, and ethyne molecules in relation to σ and π carbon-carbon bonds
2. Carbon Bonding in Organic Compounds
However, we would not be able to explain why carbon almost always forms 4 bonds, for example in the following compounds:
| Methane \((CH_4)\) | 4 \(C-H\) single bonds |
| Ethene \((CH_2=CH_2)\) |
Each carbon atom has o 1 \(C=C\) (double bond) o 2 \(C-H\) single bonds |
| Ethyne \((H-C≡C-H)\) |
Each carbon atom has |
Hence we need to introduce the concept of hybridisation to help us account for the bonding issues here
