Reaction of ethene with steam
WebCracking. is a reaction in which larger saturated hydrocarbon. molecules. are ... Steam cracking uses a higher temperature of over ... For example, ethene molecules can react together to form poly WebEthene (CH 2 CH 2) is the simplest alkene, an unsaturated hydrocarbon with a C=C double bond. Adding steam to ethene turns this alkene into a saturated molecule and adds the hydroxyl (-OH) group to one of its carbon atoms. The reaction is reversible, but we can alter the conditions to increase the yield considerably.
