CHE 201 1. Give two reasons why concentrated sulfuric acid was added to the reaction 2....
3. The esterification of butanol by sulfuric acid forms butyl hydrogen sulfate (A). This causes side products in the synthesis of bromobutane decreasing the yield of the desired product. OH + H2So. - 0-5-OH + H2O A Ö Give the IUPAC name of two possible compounds of different functional groups that are products from this side reaction. Draw a mechanism for each starting from (A). 1) Side Product 1. IUPAC name is Draw Mechanism - 2) Side Product 2, different...
What is Zaitsev’s rule? Give the mechanism for the acid-catalyzed E1 reaction of 2-butanol. Give the mechanism for the base-catalyzed E2 reaction of 2-bromobutane. Draw all possible products. You expect three products from the elimination reaction 2-butanol. What are they? The E2 mechanism is a one-step mechanism. True or False? Explain. Which of these two alcohols would you expect to be more reactive under H3PO4/aqueous conditions? Why? Give the structure of the main product in both cases. 1-phenyl-1-propanol 1 -cyclohexyl-1-propanol...
1-Butanol reaction with sodium bromide and sulfuric acid. Draw the reaction mechanism. Explain why the reaction would prefer a polar protic solvent.
QUESTIONS 1. Why does methyl benzoate dissolve in concentrated sulfuric acid? 2. What is the EQUATION for the reaction between concentrated nitric and sulfuric acids? 3. What is the DOT STRUCTURE for NO,"? 4. What is the MECHANISM for the formation of m-nitromethylbenzoate? 5. WHY does reaction occur at the META position only? 6. What is the PURITY of the m-nitromethylbenzoate recovered based on its melting range?
Why is sulfuric acid added in an Esterification reaction? (SELECT ALL THAT APPLY) a. It neutralizes base produced in the reaction. b. It pushes the reaction to completion by dehydrating the product. c. It is used as a polar protic solvent d. It activates the carbonyl of p-aminobenzoic acid making it more reactive. e. A low pH is needed for the reaction to occur Which following statement statements is wrong for Benzocaine? (SELECT ALL THAT APPLY) A. It is an...
1. Using the reaction of 2-chloro-1-methylcyclohexane with hydroxide ion, give the mechanism of Sn1 substitution. Complete the question as in question 1 2. Show how you might synthesise the following compounds given the indicated starting materials and anything else you need. In other words, show the reactions that would lead from starting materials to products. Assume that you can purify the products of each reaction. A synthesis may require more than one reaction (products of one reaction are used as starting materials in the...
1. Give IUPAC names for the following: 2. Draw the complete mechanism for the reaction if HBr with 2-methylcyclohepta-1,3-diene. Label the Lewis acid, Lewis base, nucleophile and electrophile in each step. Finally, identify the 1,2 and 1,4 products and name each product. E. We were unable to transcribe this image
QUESTIONS 1. What is the purpose of the sulfuric acid (yes, it's a catalyst, but why is it a catalyst? What is it doing that makes the reaction possible? Would the reaction just go slower without it, or would the reaction not go at all? Why?) 2. If isobutyl alcohol (2 methyl propanol) is used instead of tert butyl alcohol, a mixture of products is obtained. One the products is the same as the product obtained with the tert butyl...
