Question

Are aryl or phenyl same? If not , please elaborate.

Answer 1

They're types of organic radicals - phenyl is a specific type of aryl radical.

Explanation:

Aryl means any species created by removing a hydrogen atom from an aromatic hydrocarbon. So if you substitute chlorine, for example, for a hydrogen atom on an aromatic hydrocarbon, you have created an "aryl chloride".

Phenyl is a specific aryl radical, which is created by removing a hydrogen atom from a benzene ring. If you substitute chlorine for a hydrogen atom on benzene you create "phenyl chloride", although the IUPAC name for this would be "chlorobenzene".
