Teacher: Now, understand the problem? Solve this instance: Synchrotron radiation can generate the hydroxyl variety of these for ultrafast footprinting studies, although a more common technique involves Fentons reagent. They are typically short-lived, but may be stabilized by either HOMO (hoe-moe) or LUMO (loo-moe) interactions, or by both, as in the push-pull case. The photocatalyzed production of chloroform is a classic example of their chain reactions, which may also be initiated by azo-bis-iso-butyro-nitrile or AIBN. Diatomic oxygen is a common variety, as are the reactive oxygen species such as hydrogen peroxide which have been implicated in aging. For 10 points, name these molecules with unpaired electrons.
