If released to air, a vapor pressure of 5.21X10+4 mm Hg at 25 °C indicates ethylene will exist solely as a gas in the atmosphere. Gas-phase ethylene will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 2 days. The other sp2 hybrid orbitals form sigma bonds between C and H, therefore, leading to C-H single bonding structure. C2H4 Molecular Orbital (MO) Diagram.
