Isomers and production

[edit]

In addition tom-cymene, there are two other geometric isomers calledo-cymene, in which the alkyl groups areortho-substituted, andp-cymene, in which they arepara-substituted.p-Cymene is the most common and only natural isomer. The three isomers form the group ofcymenes.

Cymenes can be produced byalkylation oftoluene withpropylene.[1][2]
