It is the second simplest alkane. https://courses.lumenlearning.com/.../chapter/hybridization-structure-of-ethane Therefore the hybridization of the carbon atoms in this molecule is sp2 hybridization. Similar consider- ations were applied to explain the influence of carbon monoxide, which is known to increase the overall selec- tivity: like ethyne, CO adsorbs stronger than ethene and thus in the presence of CO the surface coverage of ethene remains low, even at low ethyne pressures. Apart from that, ethene is a plant hormone which can regulate the fruit ripening. All three are flammable gases. Lazonby, John. The two carbon atoms are bonded to each other through a covalent bond.
