In water,bromine is ionised up to greater extent to form large number of bromonium ions.Hence Br+ ions attack on aniline from either side to form 2,4,6,-tribromoaniline.
In order to obtain monobromo aniline,reaction is carried out in presence of acetic acid. In glacial acetic acid,bromine is ionised to lesser extent and hence relatively less number of bromonium ions are formed.Thus interference of water is ceased.
