For 10 points, a namesake "hole" in the Antarctic is deficient in what compound with formula O3?
This compound's presence can be quantified in spectrophotometry by observing an intense absorption peak at 255 nanometers; that peak is the Hartley band. Fluoroelastomers like Viton are useful in chemical-resistant gloves because they are resistant to cracking upon reaction with this compound; that cracking reaction, which is performed in the laboratory using a methanol or dichloromethane solvent at negative 78Â degrees Celsius, is a 1,3-dipolar (*) cycloaddition in which this compound cleaves alkenes. The Dobson unit was formulated to measure the concentration of this compound. In a light-catalyzed reaction, chlorine radicals break up this compound, which normally absorbs UV radiation in the stratosphere.
