This process is also called hydration. Example: The chemical reaction of water with ethene (CH 2 =CH 2 ) breaks down the C=C double bond and ethanol (CH 3 CH 2 OH) is formed by adding an H-atom on one C-atom and an OH group on the adjacent C-atom. WebThe example in the video is ethene, C 2 H 4, a symmetrical alkene reacting with Br 2 (dissolved in CCl 4). Today, we will look at a different example, which involve the addition of hydrogen halide to an unsymmetrical alkene and two possible organic products will be obtained.
