Verified. 243.9k + views. Hint: The reaction of aniline to 1, 3, 5- tribromo benzene is an electrophilic substitution reaction in which bromo groups are substituted on a benzene ring and an amino group is removed by forming diazonium salt. First, the bromination occurs resulting in formation of 1, 3, 5- tribromo aniline and then …
WebApr 19, 2008 · During bromination, 3 mL of methanol per gram of compound was added during recrystallization rather than 5 mL. Also, the bromine used was a weaker concentration than anticipated, so additional store-bought 4-bromoacetanilide was added to the product recovered. WebSep 24, 2024 · Preliminary step: Formation of the strongly electrophilic bromine cation Step 1: The electrophile forms a sigma-bond to the benzene ring, generating a positively charged benzenonium …
Web2. The nitration of aniline is going to be faster than the nitration of nitrobenzene, since the aniline is a ring with NH 2 substituent and nitrobenzene is a ring with NO 2 substiuent. As described above NH 2 is an activating group which speeds up the reaction and NO 2 is deactivating group that slows down the reaction. 3. A. the product is WebOverreaction of Aniline. Arylamines are very reactive towards electrophilic aromomatic substitution. The strongest activating and ortho/para-directing substituents are the amino (-NH 2) and hydroxyl (-OH) groups.Direct nitration of phenol (hydroxybenzene) by dilute nitric acid gives modest yields of nitrated phenols and considerable oxidative decomposition to …
WebAniline to p-bromoaniline mechanism. We know, electrons density of ortho and para positions are higher than meta positions. So, brominine subsitution should be occurred at ortho or para positions because this reaction is an electrophilic substitution reaction.. Brominum positive +1 ion forms by the reaction of FeBr 3 and Br 2.Br + is an …
