- Compounds containing a phenol group may work as ANTIOXIDANTS to prevent free radical damage. 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:Label the reactive features of the following reactants, select the most reactive feature, thenwrite and highlight what it needs. Also, state if a carbocation, carbon radical, or carbanion willstart to develop, and/or if aromatic character will be lost as a result of a reaction between thesemolecules.1,2-dimethylcyclopentene + Br2 in waterO Show how thep orbitals overlap to generate the T4* of cyclobutadiene.

- Provide the bond line structure of a compound that is able to undergo Allylic lone pair and allylic carbocation resonance. Provide all resonance structures and appropriate arrows. Indicate which resonance state is most stable and why.If you want to disrupt the ability of radicals to generate more of themselves, particularly in scenarios where they could be harmful like auto-oxidation, you need to find a suitable scavenger reagent. Such materials, known as antioxidants, succeed when they can lead to a new, more stable radical species that terminates the chain without reacting, or by further consumption of reactive radicals to generate additional non-radical species.
