When Is Benzene a Phenyl?

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.
What is difference between phenyl and benzene?
Main Difference – Benzene vs Phenyl
Most of the aromatic compounds are composed of benzene rings. Phenyl is a derivative of benzene. The main difference between benzene and phenyl is that benzene is composed of six hydrogen atoms whereas phenyl is composed of five hydrogen atoms.
Why is phenyl used instead of benzene?
For substituted benzene rings where the substituent contains more than six carbons, the benzene ring is noted by using a phenyl prefix on the alkane name. For substituted benzene rings where the substituent contains less than six carbons, the alkyl chain is added as a prefix with the ending changed to -yl.
