Hexamethylbenzene, also known as mellitene, is a hydrocarbon with the molecular formula C 12 H 18 and the condensed structural formula C 6 (CH 3) 6. It is an aromatic compound and a derivative of benzene , where benzene's six hydrogen atoms have each been replaced by a methyl group .
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
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]
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]
Alkylbenzene isomers can be differentiated by observing the position of alkyl substituents on the benzene ring using chemical ionization-proton exchange mass spectrometry. Conventional GC-MS yields limited results because the isomers have identical molecular weight and substituents.
