Ethane (/ËÉÎ¸eÉªn/ or /ËiËÎ¸eÉªn/) is an organic chemical compound with chemical formula C 2 H 6. At standard temperature and pressure, ethane is a colorless, odorless gas.Ethane is isolated on an industrial scale from natural gas, and as a byproduct of petroleum refining.he name ethane is derived from the IUPAC nomenclature of organic chemistry. Eth- refers to the presence of 2 carbon atoms, and -ane refers to the presence of a single bond between them.
carbon sigma bond is formed from overlap of an sp3 hybrid orbital on each C atom. Ethanol, C2H6O has 2(4) + 6(1) + 6 = 20 e â The two C atoms and the O atom are sp3 hybridized. All bonds are formed from overlap with these sp3 hybrid orbitals. The CâH and OâH sigma bonds are formed from overlap of sp3 hy-brid orbitals with hydrogen 1s atomic orbitals. The CâC and CâO sigma bonds are formed from overlap of the sp3 hybrid orbitals on each atom. 16. HCN, 1 + 4 + 5 = 10 valence electrons Assuming N is hybridized, both C and N atoms are sp hybridized.
