One of the first discovered was formed by reacting silver with tryphenylmethyl chloride.
The Canada Gold Medal for Science and Engineering was renamed in 2000 after Gerhard Herzberg, who won the 1971 Nobel prize in Chemistry for his work in determining the structure of molecules of this type using spectroscopy. One of the first discovered was formed by reacting silver with tryphenylmethyl chloride. The reaction between one of these molecules and an alkene drives the propagation stage of chain polymerization, and two of them are created in the initiation phase of that process. In biology, a dismutase named after one of these compounds converts that molecule into oxygen and hydrogen peroxide, a molecule which can split into two of these compounds. Including superoxide and hydroxyl, for 10 points, name this type of molecule, removed by antioxidants, Â which contain an atom with an unpaired electron.
