WebAromatic compounds are also called arenes and contain a ring of delocalised pi electrons. The most common ring is benzene (C6H6). Benzene contains six carbon atoms bonded in a hexagon shape. The bonds between each carbon atom are identical intermediates, halfway between a single and double bond in length.

Web15 dic 2024 · The aromatic ring structures in NMH coal are highly substituted and its size mainly ranges from 1 to 4 rings. Among them, single-ring aromatic compounds are dominant accounting for 54.4 mol%. 3- and 4-ring PACs mainly exist in the forms of anthracene and pyrene, respectively. Simple aromatic rings, also known as simple arenes or simple aromatics, are aromatic organic compounds that consist only of a conjugated planar ring system. Many simple aromatic rings have trivial names. They are usually found as substructures of more complex molecules ("substituted aromatics"). Typical simple aromatic compounds are benzene, indole, and pyridine.
