Please tell me what is the other name of phenol and what is the difference between phenolic OH & Alcoholic OH?

Phenol is a common name for the compound. Its IUPAC name would be benzenol, derived in the same manner as the IUPAC names for aliphatic alcohols. When a phenol molecule is substituted with additional groups, either the ortho, meta, para system or the numbering system can be employed.
Phenols are the aromatic organic compounds that have a hydroxyl group directly connected to a ring and alcohols are the non- aromatic compounds that have a hydroxyl group connected to the main chain. The difference is that one is cyclic and one is non- cyclic.
