WebIn 1932, A. A. Levine and A. G. Cole studied the ozonolysis of o -xylene and isolated three products: glyoxal, butane-2,3-dione, and pyruvaldehyde: In what ratio would you expect the three products to be formed if o -xylene is a resonance hybrid of two structures? WebVolatile organic compounds (VOCs) play an important role in atmospheric chemistry. Primary VOCs take part in chemical and photochemical reactions, contributing to ozone (O3) and secondary organic aerosol (SOA) formation, which may cause air pollution problems. High VOC concentrations might lead to dizziness, nausea, headaches, genotoxicity, …
Webo-xylene has two resonance structures: All three products, i.e., methyl glyoxal, 1, 2-dimethylglyoxal, and glyoxal are obtained from two Kekule structures. Since all three products cannot be obtained from any one of the structures, this proves that o-xylene is a resonance hybrid of two Kekule structures (I and II).
