Choose the incorrect statement Aniline undergoes Friedel-Crafts reactions. OA B. Using (1) HCI, H20, heat and (2) HO-to remove (deprotect) the acetyl group back to amino group, The amino group on aniline can be protected by acetylation step. Halogenation of benzene with a strong activating substitutent does not require FeBrz. D. Friedel-Crafts acylations will not occur if there is a meta-director already on the benzene ring. E. 000 30 М.
Please help... Need a detail Mechanism of this reaction. Thanks... Electrophilic aromatic substitution describes the reaction where a hydrogen from a benzene ring is replaced by an electrophile. Halogenation, nitration, sulfonation, alkylation and acylation are all possible using this type of reaction. The electrophile attacks the pi electrons of the aromatic ring, yielding a benzenonium ion. The substituted aromatic product is obtained when a proton is lost, restoring the aromatic system. If there is a substituent on the aromatic ring...
Consider the -N=O group and describe its directing properties in electrophilic aromatic substitution. The -N=O is a ortho,para/meta director because of: -induction away from the ring -resonance into the ring -induction towards the ring -resonance away from the ring
(V) 10pts. When aniline (C6H3-NH2) reacts with bromonium ion (NO2. the nitro group can become bonded to a carbon at one of the three possible positions: ortho, meta, and para to the -NH2 group in the benzene ring. Consider meta and ortho attack and draw RESONANCE STRUCTURES for the carbocations that result when NO2 undergoes electrophilic aromatic substitution to aniline. Then, on the basis of these resonance structures, explain whether the --NH2, group.is meta director, or ortho/para director. Show which...
