Buy Ethylene (ethene) Cas 74-85-1
Ethylene (IUPAC name: ethene) is a hydrocarbon which has the formula C2H4 or H2C=CH2. It is a colourless, flammable gas with a faint “sweet and musky” odour when pure.[7] It is the simplest alkene (a hydrocarbon with carbon–carbon double bonds).
Ethylene is widely used in the chemical industry, and its worldwide production (over 225 million tonnes in 2022)[8] exceeds that of any other organic compound.[9][10] Much of this production goes toward creating polyethylene, which is a widely used plastic containing polymer chains of ethylene units in various chain lengths. Production emits greenhouse gases, including methane from feedstock production and carbon dioxide from any non-sustainable energy used. Buy Ethylene (ethene) Cas 74-85-1
Ethylene is also an important natural plant hormone and is used in agriculture to induce ripening of fruits.[11] The hydrate of ethylene is ethanol.
Structure and properties
This hydrocarbon has four hydrogen atoms bound to a pair of carbon atoms that are connected by a double bond. All six atoms that comprise ethylene are coplanar. The H-C-H angle is 117.4°, close to the 120° for ideal sp² hybridized carbon. The molecule is also relatively weak: rotation about the C-C bond is a very low energy process that requires breaking the π-bond by supplying heat at 50 °C.[citation needed]
The π-bond in the ethylene molecule is responsible for its useful reactivity. The double bond is a region of high electron density, thus it is susceptible to attack by electrophiles. Many reactions of ethylene are catalyzed by transition metals, which bind temporarily to the ethylene using both the π and π* orbitals.[citation needed]
Being a simple molecule, ethylene is spectroscopically simple. Its UV-vis spectrum is still used as a test of theoretical methods. Buy Ethylene (ethene) Cas 74-85-1
