A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
The C 2 benzenes are a class of organic aromatic compounds which contain a benzene ring and two other carbon atoms. For the hydrocarbons with no further unsaturation, there are four isomers. There are three xylenes and one ethylbenzene .

[1] [2] Simple aromatic rings can be heterocyclic if they contain non-carbon ring atoms, for example, oxygen, nitrogen, or sulfur. They can be monocyclic as in benzene, bicyclic as in naphthalene, or polycyclic as in anthracene. Simple monocyclic aromatic rings are usually five-membered rings like pyrrole or six-membered rings like pyridine.
The compound in which a benzene ring is fused to arsole — typically on the carbon atoms 3 and 4 — is known as benzarsole. [3] Cumene (C 9 H 12), an aromatic hydrocarbon used in the production of phenol and acetone. Cummingtonite ((Mg,Fe 2+) 2 (Mg,Fe 2+) 5 Si 8 O 22 (OH) 2), a magnesium-iron silicate hydroxide, first identified in Cummington ...
Also known as diphenylbenzenes or triphenyls, they consist of a central benzene ring substituted with two phenyl groups. There are three substitution patterns: ortho-terphenyl, meta-terphenyl, and para-terphenyl. Commercial grade terphenyl is generally a mixture of the three isomers.
Benzothiazine is a heterocyclic compound consisting of a benzene ring attached to the 6-membered heterocycle thiazine. The name is applied to both the 2H- and 4H-isomers of the molecule. 2,1-Benzothiazine, a type of benzothiazines was first reported in the 1960s. Subsequently, their preparation and intensive biological and physiological studies ...
Coronene (also known as superbenzene and cyclobenzene) is a polycyclic aromatic hydrocarbon (PAH) comprising seven peri-fused benzene rings. [10] Its chemical formula is C 24 H 12. It is a yellow material that dissolves in common solvents including benzene, toluene, and dichloromethane. Its solutions emit blue light fluorescence under UV light.
