Witryna23 sty 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 … WitrynaProcedure. Prepare a 250 cm 3 beaker of boiling water to act as a water bath. If using a Bunsen burner, keep all other chemicals well away from the flame. Add 0.1 g of di (dodecanoyl) peroxide to 5 cm 3 of phenylethene in a boiling tube. Fit a bung carrying a 20 cm length of glass tubing in the top of the boiling tube.
