Why is m-nitro formed in the reaction of nitration of methyl benzoate instead of the ortho or para isomers? Theoretically, do you expect a m-product during sulfonation of methyl benzoate? Explain.

When methyl benzoate bears a substituent at the para position, the rate of hydrolysis of the ester group depends on the nature of the substituent at the para position. Apparently, a methoxy substituent renders the ester less reactive, while a nitro substituent renders the ester more reactive. Explain this observation.

aromatic amines are mor more basic the amine of aniline
Aromatic amines are more basic than the amine of aniline if NH2 aniline Select one: The nitrogen lone pair is part of a sulfonamide, The nitrogen has a positive charge as in a quaternary amine. The nitrogen lone pair is involved in resonance with a carbonyl group. The aromatic ring is substituted with electron donating groups. The aromatic ring is substituted with electron withdrawing groups. Choose the correct product for...

(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...

(ORGANIC CHEM LAB QUESTION) In the synthesis of the Dye Para Red from Aniline: The yield is almost quantitive in the 1st step, most of the class obtained an abysmal yield in the 2nd step, can an analysis be made as to why the yield is so low in this step? PLEASE HELP!!!!

-NH2 is one of the most powerful ortho/para activators in electrophilic aromatic substitution. However, attempts to nitrate aniline under standard conditions leads to the formation of m-nitroaniline (3%) with 97% of aniline remaining unchanged. Why is this? Hint: -NH2 is a base as well as an activator. 3. Why are amines more activating than amides? NH2 Aniline is very readily brominated in aqueous conditions at room temperature in comparison to benzene (high temperature and FeBr3 catalysis is required). When aniline...
