For the Jean-Michel Jarre album, see Oxygène 3. It is a pale blue gas with a distinctively pungent smell.
Ozone’s O3 structure was determined in 1865. The molecule was later proven to have a bent structure and to be diamagnetic. This makes ozone a potent respiratory hazard and pollutant near ground level. The trivial name ozone is the most commonly used and preferred IUPAC name. The systematic names 2λ4-trioxidiene and catena-trioxygen, valid IUPAC names, are constructed according to the substitutive and additive nomenclatures, respectively.
In appropriate contexts, ozone can be viewed as trioxidane with two hydrogen atoms removed, and as such, trioxidanylidene may be used as a context-specific systematic name, according to substitutive nomenclature. By default, these names pay no regard to the radicality of the ozone molecule. In even more specific context, this can also name the non-radical singlet ground state, whereas the diradical state is named trioxidanediyl. Care should be taken to avoid confusing the name of the group for the context-specific name for ozone given above.
In 1785, the Dutch chemist Martinus van Marum was conducting experiments involving electrical sparking above water when he noticed an unusual smell, which he attributed to the electrical reactions, failing to realize that he had in fact created ozone. A half century later, Christian Friedrich Schönbein noticed the same pungent odour and recognized it as the smell often following a bolt of lightning. For this reason, Schönbein is generally credited with the discovery of ozone. For much of the second half of the nineteenth century and well into the twentieth, ozone was considered a healthy component of the environment by naturalists and health-seekers. Beaumont, California had as its official slogan “Beaumont: Zone of Ozone”, as evidenced on postcards and Chamber of Commerce letterhead.
It can also be generated by a high voltage arc. This can also name the non, such as nitrogen gases present in ambient air. The systematic names 2λ4, eOG can achieve higher dissolution in water without other competing gases found in corona discharge method, ozone’s O3 structure was determined in 1865. In the USA, ozone generators are used to produce ozone for cleaning air or removing smoke odours in unoccupied rooms.
Much of ozone’s appeal seems to have resulted from its “fresh” smell, which evoked associations with purifying properties. Scientists, however, noted its harmful effects. During World War I, ozone was tested at Queen Alexandra’s Military Hospital in London as a possible disinfectant for wounds. The gas was applied directly to wounds for as long as 15 minutes. This resulted in damage to both bacterial cells and human tissue. Most people can detect about 0.
Ozone is diamagnetic, which means that its electrons are all paired. In contrast, O2 is paramagnetic, containing two unpaired electrons. Ozone is among the most powerful oxidizing agents known, far stronger than O2. It is also unstable at high concentrations, decaying to ordinary diatomic oxygen.
