Q: The hydroxyl radical is highly reactive because it has what? Read this paragraph and choose the correct option from the provided answers: Because the hydroxyl radical has an unpaired electron, it is highly reactive. (This is true of any substance with unpaired electrons, known as a free radical. ) This hydroxyl radical can react with all kinds of biological molecules (DNA, proteins, enzymes, and so on), causing damage to the molecules and disrupting physiological processes. Examples of direct and indirect damage are shown in Figure 21.32. Choices: - unpaired neutron - paired proton - paired electron - unpaired electron A:
unpaired electron

Q: Q: What type of electrons are electrons that are not confined to the bond between two atoms? Read this paragraph and choose the correct option from the provided answers: In benzene, the true bonding between carbon atoms is neither a single nor a double bond. Rather, all of the bonds are a hybrid of a single and double bond. In benzene, the pi bonding electrons are free to move completely around the ring. Delocalized electrons are electrons that are not confined to the bond between two atoms, but are instead allowed to move between three or more. The delocalization of the electrons in benzene can best be shown by showing benzene with a ring inside the hexagon, with the hydrogen atoms understood. Choices: - virtualized - detached - internalized - delocalized A:
A: delocalized
