- 6) If you are given a mixture consisting of following 3 compounds, explain how you would separate the components by solvent extraction method NH2 ÇOOH (A) Cyclopentylamine (B) 2,4-Cyclopentadiene-1-carboxylic acid (C) Benzenearrow_forwardKevlar®, a polymeric aromatic amide, is synthesized from the monomers p-phenylenediamine (left) and terephthaloyl chlo-ride (right). The polymer strands are initially aligned randomly,but they are dissolved and spun to give a lightweight, flexible product that is five times stronger than steel of the same weight.(a) Describe this step in terms of a Lewis acid-base reaction. (b) Would you expect water or ammonia to react faster with an acid chloride? Explain.arrow_forwardWrite a structural formula for each of the following compounds: (a) m-Chlorobenzoyl chloride (b) Trifluoroacetic anhydride (c) cis-1,2-Cyclopropanedicarboxylic anhydride (d) Ethyl cycloheptanecarboxylate (e) 1-Phenylethyl acetate (f) 2-Phenylethyl acetate (g) p-Ethylbenzamide (h) N-Ethylbenzamide (i) 2-Methylhexanenitrilearrow_forward

(i) Using your knowledge of silicon chemistry, explain why the synthesis of a compound containing a formal Si=0 double bond is challenging. (ii)Bearing in mind your answer to part (i), suggest a synthetic route to a silanone, R2Si=O, starting from silicon tetrachloride SiCl4 and using any other reagents you choose. Identify all reagents and side-products in your synthetic route and specify your chosen R group, giving reasons for your choice.arrow_forward

(a) Assuming that each reaction is performed in the gas phase only, and that no additional chemicals are required, calculate (i) the atom economy and (ii) the effective mass yield of both reactions. You should assume that O₂, CO₂ and H₂O are not toxic. (b) Which route would you recommend to industry? Outline the factors which might influence your decision.arrow_forward(b) (d) (b) The following reactions as written will NOT give the indicated product. For each of the reactions explain (a) НО (i) (ii) (iii) OH The reason why the reaction as written will not occur; How the reaction could be modified to give the indicated product (may include the use of alternative or additional reagents); What should be the outcome for the reactions as written?

- Which of this reactants can be used to generate the product on the top?arrow_forward9. Phosphotyrosine (shown below) has four ionizable functional groups (pK1 = 2.5, pKR1 = 2.1, pKr2 = 7.2, pK2 = 9.5). (a) Write the equilibrium equation for its four ionization forms and assign the proper pka for each ionization. DRAW the structure of phosphotyrosine in each ionization state. What is the net charge on the phosphotyrosine molecule in each ionization state? *H3N. pk2 - 9.5 .COOH pK, - 2.5 O=P-OH pKRI - 2.1 ÖH pKRI - 7.2 (b) Draw the titration curve of phosphorotyrosine and indicate each pKa and the isoelectric point (pl), indicate the molar equivalents of OH on the x-axis.arrow_forwardSome of the most useful compounds for organic synthesisare Grignard reagents (general formula R-MgX, where X is ahalogen), which are made by combining an alkyl halide, R-X,with Mg. They are used to change the carbon skeleton of a start-ing carbonyl compound in a reaction similar to that with R-Li:.(a) What is the product, after a final step with water, of thereaction between ethanal and the Grignard reagent of bromo-benzene? (b) What is the product, after a final step with water, ofthe reaction between 2-butanone and the Grignard reagent of2-bromopropane? (c) There are often two (or more) combina-tions of Grignard reagent and carbonyl compound that will givethe same product. Choose another pair of reactants to give theproduct in (a). (d) What carbonyl compound must react with aGrignard reagent to yield a product with the -OH group at theendof the carbon chain?
