When benzene is used and when phenol is used❓

Answer» In easy way benzene is a closed ring having molecular formula C6H6 but if we replace one hydrogen of benzene with --OH group then we can say its iupac name as benzen-1-ol or simply " Phenol" .Phenol will have molecular formula as C6H6O
Phenyl name is used when you can no longer use Benzene as a parent name in IUPAC system of naming and it must be used as a substituent.
