Friedel crafts alkylation of nitrobenzene
WebNitrobenzene does not undergo Friedel-Craft's alkylation because the nitro group is a very strong electron-withdrawing group, which makes the aromatic system that its attached to very electron-poor. Web5 questions: 1-Describe the rules to determine if a compound is aromatic, non-aromatic or anti-aromatic. Give one example for each category. 2-In the IR spectrum, in which region would you find overtones? 3-What are the main limitations of an Friedel-Crafts alkylation reaction? 4-Why is sulfonation very important? 5-When naming a compound, the aniline …
