Web2. At school, we are taught that in bromine water, the following equilibrium is present: B r X 2 + H X 2 O ⇌ B r O H + H B r. Therefore, when you add an alkene to bromine water, you don't get bromination, but rather the B r O H reacts instead and you get the following reaction (lets say for ethene for example): C X 2 H X 4 + B r O H C X 2 H X ... 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) … optical visor
