- How does bromobenzene react differently from benzyl chloride under SN1 and SN2 conditions, and why?arrow_forwardSuggest a reason why the NH2 group depicted in the reaction scheme is the one used to form the semicarbazone and not the other NH2 group.arrow_forwardSuggest an explanation for the fact that the order of reactivity of the halides toward n-butylbrosylate in acetone is Cl” > Br” > I~ when (C4H9)4N* is the cation of the halide salt butI” > Br” > Cl” when Li’ is the cationarrow_forward
- Explain how benzaldehyde and dimedone reacts with each other, and then with the aminotriazole to form compound 1a in the presence of an acid catalyst. Provide a detailed reaction mechanism. During the development of the optimized procedure for the experiment, it was found out that compound 1b can also be produced from the same set of starting materials. Propose a detailed reaction mechanism for the formation of 1b. Explain your answer. What factor/s may drive the formation of 1b over 1a?arrow_forwarda) Give the appropriate base for the above reaction and draw the resonance structures of the enolate ions derived from compound A. Then write the mechanism for the formation of the Dieckmann cyclized product B. b) If compound B above is reacted with NaBH 4 , draw the structure of the reduced product. Give a reason for your choice of product. c) Being a β-ketoester, B could undergo a 3-step synthesis involving alkylation, hydrolysis and decarboxylation reactions to yield the cyclopentanone, C. Write the outline synthesis for each step which include the appropriate regents and correct intermediate.arrow_forwardA) Provide the reagent and reaction mechanism to show how the reactants and products in the following reaction can interconvert B) under what conditions would the reaction I) favour reactants, II) favour the products and III) why?arrow_forward
- Electrophilic nitration of benzoic acid gives almost exclusively 3-nitrobenzoic acid. By drawing the appropriate resonance forms of the intermediate cations resulting from attack of [NO2]+, explain this result.arrow_forward3. Obtain acetophenone and acetaldehyde by reaction of glycols with periodic acid. Justify your answer with the reaction mechanism.arrow_forwardArrange the following in ascending order of reactivity for the preparation of the corresponding coumarins. Explain your answers.arrow_forward
- (a) Write the structures of main products when benzene diazonium chloride reacts with the following reagents :(i) H3PO2 + H2O (ii) CuCN/KCN (iii) H2O(b) Arrange the following in the increasing order of their basic character in an aqueous solution :C2H5NH2, (C2H5)2NH, (C3H5)3N(c) Give a simple chemical test to distinguish between the following pair of compounds :C6H5—NH2 and C6H5—NH—CH3arrow_forwardThe azo compound shown below has a λmax value of 410 nm. When treated with hydrogen in the presence of palladium on carbon, the λmax changes significantly. Suggest a reason for this observation and predict whether the λmax value increases or decreases.arrow_forwardGiven the sequence of reactions shown below assume the reactions are stoichiometric fill in the reagents needed for steps A B and C and explain what happens in each step of the reactions, by also namearrow_forward
