 Principle functional group is the methylbenzene therefore root =
toluene
 There is a bromine substituent therefore bromo
 There is a chlorine substituent therefore chloro
 Numbering from the CH_{3} (priority group at C1) gives
the substituents the locants = 2 and 4
2bromo4chlorotoluene


 Principle functional group is the aromatic alcohol therefore = phenol
 There are two C1 substituents therefore dimethyl
 Numbering from the OH (priority group at C1) gives the substituent
the locant = 3,5
3,5dimethylphenol


 Principle functional group is the aromatic amine therefore = aniline
 There is a C1 substituent therefore methyl
 There is a C2 substituent therefore ethyl
 Numbering from the NH_{2} (priority group at C1) gives
the substituents the locants = 2 and 3
2ethyl3methylaniline
