It is one of the three isomers of trimethylbenzene. It is used in jet fuel, mixed with other hydrocarbons, to prevent the formation of solid particles which might damage the engine. German chemist Oscar Jacobsen first prepared the hydrocarbon in 1882 and designated it hemellitol as a reference to the trivial name of hexamethylbenzene. [4]
The chemical formula for all the saturated isomers is C 9 H 12. There are three trimethylbenzenes , three ethylmetylbenzenes, and two propylbenzene isomers. Petrol (gasoline) can contain 3-4% C 3 -benzenes.
[1] [2] Through their different arrangement, they form three structural isomers with the molecular formula C 9 H 12. They also belong to the group of C 3 -benzenes . The best-known isomer is mesitylene .
The C 2 benzenes are a class of organic aromatic compounds which contain a benzene ring and two other carbon atoms. For the hydrocarbons with no further unsaturation, there are four isomers.
IUPAC names can sometimes be simpler than older names, as with ethanol, instead of ethyl alcohol. For relatively simple molecules they can be more easily understood than non-systematic names, which must be learnt or looked over. However, the common or trivial name is often substantially shorter and clearer, and so preferred. These non ...
Dewar benzene (also spelled dewarbenzene) or bicyclo[2.2.0]hexa-2,5-diene is a bicyclic isomer of benzene with the molecular formula C 6 H 6.The compound is named after James Dewar who included this structure in a list of possible C 6 H 6 structures in 1869. [1]
