What are the key differences between phenol and phenyl, and how do these differences impact their chemical properties and reactivity?

Phenol is a specific compound with a hydroxyl group attached to a benzene ring, while phenyl refers to just the benzene ring without any other functional groups. The presence of the hydroxyl group in phenol makes it more reactive than phenyl. Phenol can participate in hydrogen bonding and undergo reactions like oxidation and substitution, while phenyl is less reactive and mainly serves as a structural component in organic molecules.
