Hydrocarbons, Aromatic

Add to MyChemicals

There are 265 chemical datasheets assigned to this reactive group.

What are reactive groups?

Reactive groups are categories of chemicals that typically react in similar ways because they are similar in their chemical structure. Each substance with a chemical datasheet has been assigned to one or more reactive groups, and CAMEO Chemicals uses the reactive group assignments to make its reactivity predictions. More info about reactivity predictions...

If you can't find a chemical in the database--but you know what reactive group it belongs in--you can add the reactive group to MyChemicals instead in order to see the reactivity predictions.

Flammability
Aromatic hydrocarbons are all combustible. The lightest members of this class, benzene and substituted benzenes, have high enough vapor pressures and low enough flash points to be vapor explosion hazards.
Reactivity
Vigorous reactions, sometimes amounting to explosions, can result from the contact between these materials and strong oxidizing agents. Substitution at the benzene nucleus occurs by halogenation (with an acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction.
Toxicity
Many aromatic hydrocarbons are poisons by inhalation and irritants to the skin and eyes. Some are poisons by skin contact. Aromatic hydrocarbons are very often carcinogenic (benzene is an example).
Other Characteristics
Compounds in this group contain the benzene nucleus. In benzene, six carbon atoms form a ring maintained by alternating single and double bonds; each carbon atom is also bonded to a hydrogen atom. Aromatic hydrocarbons possess a single benzene nucleus with side-groups replacing one or more of the hydrogen atoms or in fused sets of two or more rings. Aromatic hydrocarbons with multiple fused rings (polycyclic aromatic hydrocarbons, or PAHs) are common air contaminants.
Examples
Benzene, toluene, naphthalene, pyrene, anthracene, chrysene, acenaphthylene, xylene, benzo[a]pyrene, biphenyl, cumene, fluorene, phenanthrene.
