This is accomplished when a free radical (or UV light) encounters a phenol group, turning the phenol group into a radical. However, contrary to typical radical behavior, the structure of the phenol radical can neutralize (or quench) the unpaired electron. Specifically, the phenol structure neutralizes (or quenches) the unpaired radical electron by doing the following: taking the electron and ---------. The correct name (or abbreviation) of an example compound (discussed in the lecture videos) containing a phenol group with antioxidant properties is: ---------.Complete the equation for the following proton-transfer reaction by using curved arrows to show the flow of electron pairs and drawing the products of the reaction. • Draw all atoms, including hydrogen atoms.
