WebJan 23, 2024 · Benzene reacts with chlorine or bromine in an electrophilic substitution reaction, but only in the presence of a catalyst. The catalyst is either aluminum chloride (or aluminum bromide if you are reacting benzene with bromine) or iron. Strictly speaking iron is not a catalyst, because it gets permanently changed during the reaction. WebJan 23, 2024 · The organic product is (chloromethyl)benzene. The brackets in the name emphasizes that the chlorine is part of the attached methyl group, and isn't on the ring. One of the hydrogen atoms in the methyl group has been replaced by a chlorine atom, so this is a substitution reaction. high school mod minecraft

WebThe Nitration of Methylbenzene (Toluene) Methylbenzene reacts rather faster than benzene – in nitration, the reaction is about 25 times faster. That means that you would use a … WebThe 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 WebAlso, as noted earlier, toluene undergoes nitration about 25 times faster than benzene, but chlorination of toluene is over 500 times faster than that of benzene. What is chlorination of benzene? Benzene reacts with chlorine or bromine in the presence of a catalyst, replacing one of the hydrogen atoms on the ring by a chlorine or bromine atom. high school mod in among us
