When is benzene a phenyl?
Since this rule states that the benzene ring will act as a functional group (substituent) whenever a substituent with more than six (6) carbon atoms is attached to itthe name « benzene » is changed to phenyl, which is used in the same way as any other substituent, such as methyl, ethyl, or bromine.
What is the difference between phenyl and benzene?
Main Difference – Benzene vs Phenyl
Most aromatic compounds consist of benzene rings. Phenyl is a derivative of benzene.The main difference between benzene and phenyl is that Benzene consists of six hydrogen atoms while phenyl consists of five hydrogen atoms.
Why use phenyl instead of benzene?
For substituted benzene rings wherein the substituent contains more than six carbons, the benzene ring is indicated by using the phenyl prefix on the alkane name. For substituted benzene rings whose substituents contain less than six carbon atoms, add an alkyl chain as a prefix and change the end to -yl.
