15.1: Naming the Benzenes - Chemistry LibreTexts
The benzyl group (abbv. Bn), similar to the phenyl group and can be written as C 6 H 5 CH 2-R, PhCH 2-R, or Bn-R. Nomenclature of benzyl group based compounds are very similar to the phenyl group compounds. For example, a chlorine attached to a benzyl group would simply be called benzyl chloride, whereas an OH group attached to a benzyl group ...
15.3: Nomenclature of Benzene Derivatives - Chemistry LibreTexts
As this rule suggests that the benzene ring will act as a function group (a substituent) whenever a substituent of more than six (6) carbons is attached to it, the name "benzene" is changed to phenyl and is used the same way as any other substituents, such as methyl, ethyl, or bromo.

Ethylbenzene - Wikipedia
Ethylbenzene is an organic compound with the formula C6H5CH2CH3. It is a highly flammable, colorless liquid with an odor similar to that of gasoline. This monocyclic aromatic hydrocarbon is important in the petrochemical industry as a reaction intermediate in the production of styrene, the precursor to polystyrene, a common plastic material.

Naming aromatic compounds - chemguide
The nitro group, NO 2, is attached to a benzene ring. The simplified formula for this is C 6 H 5 NO 2. methylbenzene. Another obvious name - the benzene ring has a methyl group attached. Other alkyl side-chains would be named similarly - for example, ethylbenzene. The old name for methylbenzene is toluene, and you may still meet that.

By replacing one or more of the hydrogen atoms with some functional group, we get several benzene compounds. While naming the substituted benzene compounds, we prefix the name of the substituent to the word benzene. In this article, we will learn the IUPAC nomenclature of the substituted benzene compounds.
