If bromine is an EWG, why does the nitration of bromobenzene result is para and ortho products in an Electrophilic Aromatic Substitution reaction?
If bromine is an EWG, why does the nitration of bromobenzene result is para and ortho...
Nitration of phenols is a classic example of an electrophilic aromatic substitution reaction. a) Why does the nitration of phenol (hydroxybenzene) proceed only in the ortho- and para-positions on the ring? b) Draw the resonance structures that highlight the ortho- and para-directing nature of hydroxy substituents. Make sure to include the structures that showcase the movement of the charges in the ring.
In nitration of acetanilide(synthesis of p-nitroaniline) main product is ortho and para. Explain why ortho and para product is major in resonance and mechanism term.
Sort the following molecules by whether the substituent group is ortho/para or meta directing for electrophilic aromatic substitution. Sort the following molecules by whether the substituent group is ortho/para or meta directing for electrophilic aromatic substitution.
DRAW ALL THE RESONANACE STRUCTURES THAT WOULD RESULT FROM ELECTROPHILIC AROMATIC SUBSTITUTION OF THE ORTHO, META, AND PARA POSITIONS OF THE AROMATIC COMPOUND SHOWN BELOW. IDENTIFY ANY PARTICULAR STABLE OR UNSTABLE INTERMEDIATES AND DETERMINE IF THE SUBSTITUTION IS ORTHO, PARA, OR META DIRECTING BASED ON THE RELATIVE STABILITY OF THE INTERMEDIATES. -t Br meta.
Add the following questions to the final report: a) Why does the carbomethoxy group directs the reaction to positions that are meta to it? b) Why the formation of dinitrobenzaote is substantially disfavored ? c) Would you expect small amounts of the ortho and para substituted product? How would you remove them if they are formed ? d) Why does water have a retarding effect on the nitration ? e) Explain why Benzene has lower reactivity in electrophilic addition reactions...
