English: Newman projections of ethane conformations & their relative energy differences (not total energies). Conformations form when ethane rotates about one of its single covalent bond. Torsional/dihedral angle is shown on x-axis. Conformations (according to IUPAC): A: staggered B: eclipsed
Comparison of bond lengths in simple hydrocarbons [5] Molecule Ethane: Ethylene: Acetylene: Formula C 2 H 6: C 2 H 4: C 2 H 2: Class alkane: alkene: alkyne: Structure Hybridisation of carbon sp 3: sp 2: sp C-C bond length 153.5 pm: 133.9 pm: 120.3 pm: Proportion of C-C single bond 100% 87% 78% Structure determination method microwave ...
Ethane (US: / ˈ ɛ θ eɪ n / ETH-ayn, UK: / ˈ iː θ eɪ n / EE-thayn) is a naturally occurring organic chemical compound with chemical formula C 2 H 6. At standard temperature and pressure, ethane is a colorless, odorless gas. Like many hydrocarbons, ethane is isolated on an industrial scale from natural gas and as a petrochemical by ...
Relative conformation energy diagram of butane as a function of dihedral angle. [9] A: antiperiplanar, anti or trans. B: synclinal or gauche. C: anticlinal or eclipsed. D: synperiplanar or cis. [2] Rotating their carbon–carbon bonds, the molecules ethane and propane have three local energy minima.
A bond between a hydrogen atom and an sp 2 hybridised carbon atom is about 0.6% shorter than between hydrogen and sp 3 hybridised carbon. A bond between hydrogen and sp hybridised carbon is shorter still, about 3% shorter than sp 3 C-H. This trend is illustrated by the molecular geometry of ethane, ethylene and acetylene.

In condensed structural formulas, many or even all of the covalent bonds may be left out, with subscripts indicating the number of identical groups attached to a particular atom. Another shorthand structural diagram is the skeletal formula (also known as a bond-line formula or carbon
In ethene, the two carbon atoms form a σ bond by overlapping one sp 2 orbital from each carbon atom. The π bond between the carbon atoms perpendicular to the molecular plane is formed by 2p–2p overlap. Each carbon atom forms covalent C–H bonds with two hydrogens by s–sp 2 overlap, all with 120° bond angles. The hydrogen–carbon bonds ...
The bond angle for a symmetric tetrahedral molecule such as CH 4 may be calculated using the dot product of two vectors. As shown in the diagram at left, the molecule can be inscribed in a cube with the tetravalent atom (e.g. carbon) at the cube centre which is the origin of coordinates, O. The four monovalent atoms (e.g. hydrogens) are at four ...
