Mancude monocyclic hydrocarbons without side chains of the general formula
CnHn (
n is an even number) or
CnHn+1 (
n is an odd number). In systematic nomenclature an annulene with seven or more carbon atoms may be named [
n]annulene, where
n is the number of carbon atoms, e.g. [9]annulene for cyclonona-1,3,5,7-tetraene.
