WebJan 23, 2024 · Ethene is the formal IUPAC name for H 2 C=CH 2, but it also goes by a common name: Ethylene. The name Ethylene is used because it is like an ethyl group ( C H 2 C H 3) but there is a double bond between the two carbon atoms in it. Ethene has the formula C 2 H 4 and is the simplest alkene because it has the fewest carbons (two) … WebWith HBr, ethene readily reacts and give ethyl bromide (bromoethane) as the product.
