3. Consider the electrophilic aromatic substitution reaction below. Draw three resonance structures of the arenium cation intermediate resulting from para attack. Of these three, indicate one which would be a relatively stable resonance contributor. Finally, provide a possible justification for the fact that the major product here would be the para product, while the ortho product is formed as a minor product (only trace amounts of meta product are formed).

From a Nucleophilic aromatic substitution (SNA), analyze 2 possible disonnections and conclude which bond is convenient disconnect. Taking into consideration the above, suggest a retro-synthesis and a synthesis for the following molecule. (Lobenzarit)
Consider the reaction: Draw out the two possible substitution reaction pathways (SN1 and SN2) and include all possible products. Include the structure of any intermediates and provide the curly arrow mechanisms required for both pathways. Using your answer to the above, justify which reaction pathway (SN1 or SN2) is more likely to occur
Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. What is the purpose of deprotonation in the last step of electrophilic aromatic substitution? A) To neutralize the base that is present B) To make room for the electrophile C) To make the ring more reactive D) To restore an aromatic system E) None of the above
Could you please help me with this question? The reaction shown below does not follow the expected theory. Given what you learned about substitution/elimination, what is the expected mechanism this reaction should follow? Suggest why that is not what happens and give the actual product of the reaction.
Shown below are two reactions; Reaction 1 is a Friedel-Crafts acylation while Reaction 2 is a Friedel- Crafts alkylation. State which reaction will occur faster and justify your answer, with words and structures. Mention: e- density / Deactivation / Resonance stable / faster the carbonation formed because it's gonna have smaller activation energy
The product in this reaction is basic enough to be protonated by a dilute HCl solution. Draw the protonated species, clearly showing where protonation occurs. Draw all possible resonance structures of the conjugate acid of the product, and use these to explain why the product is so much more basic than a typical ester, like ethyl acetate.
Aromatic heterocycles can undergo electrophilic aromatic substitution like benzene. Groups attached to the heterocycle can therefore have similar directing effects as they can on benzene. Keeping this in mind, consider the following reaction, where E+ is a general electrophile: a) Draw all relevant resonance structures for the intermediate of each product b) Based on your answers to part a), which product do you expect to be the major product and why? (2 points)c) If you performed this reaction in the laboratory, which instrumental technique (ex: 1H NMR, IR, Mass Spectrometry) would be best to determine which product you obtained of the three and why?
Any help with this would be great! Explanations definitely welcome, thanks in advance for any help:) What is the major product of the reactions?
how would you deconstructing” a target molecule into its readily available, simple starting materials for this reaction: (AKA 'retrosynthesis')
Some of the groups pre-bonded to an aromatic ring cause electrophilic aromatic substitution to occur mainly at the ortho and para sites. Others lead to the meta location. Is that true or false?
(a) For which aromatic compound do you expect nitration to take place faster: furan or thiophene? (b) For each of these compounds, at which C atom do you expectelectrophilic aromatic substitution to predominantly takeplace? Explain your reasoning.
What are the sequences of reactions that must occur to make the target compounds on the left from the starting compounds on the right. INCLUDE STRUCTURES OF ALL INTERMEDIATES AND LABEL THEM PLEASE. Thanks!
