Sulfonation is the only reversible substitution reaction acting on this class of compounds.
Sulfonation is the only reversible substitution reaction acting on this class of compounds. In these hydrocarbons, the carbon atoms have sp2 hybridization and a planar structure, while the carbon-hydrogen ratio is very small. The simplest polycyclic one is pentalene, while napthalene and phenol also belong in this category. According to Huckle's rule, if the number of delocalized electrons is equal to 4n plus two, where n is a nonnegative integer, a compound is said to be this. Undergoing electrophilic rather than nucleophilic substitution reactions, FTP, identify these opposites of aliphatic compounds which contain their namesake carbon rings and whose name suggests olfactory pleasantness.
