Plzz help..Its a big doubt..


In nomenclature for aromatic compounds , when do we use "phenyl". Is its C6H5 or any side chain on the ring compound..


Is its for side chain , then if NO2 group is there on the ring , why we write nitrobenzene & not phenylbenzene?

if from benzene a hydrogen is removed then the compound C6H5 is called phenyl.


but if a group ex. N02 is attached then it is no more a free phenyl, as in place of hydrogen a group is attached (no vacant place). thus it is called differently as nitrobenzene.
