- Fill in the missing reagent/product(s) for the following reactions.2. Draw the structures and explain why CH3CH₂O and CH3CO₂ are good nucleophiles but CH3SO3, water, and alcohols (R-OH) are poor nucleophiles. Propose a 'cutoff' for the amount of negative charge needed to be a good nucleophile. CH3CH₂O CH3CO₂ CH3SO3 H₂O CH₂OHExplain why the trifluoromethane sulfonate (TfO-) ion is a better leaving group than the methanesulfonate (MsO-) ion.
- The question is: "Draw the curved arrow mechanism for the reaction between pentan-2-one and (CH3)3O– in t-butanol to form an enolate. Draw all electrons and charges on both resonance structures. Then answer the question about the reaction." I got the initial arrows correct, but am not entirely sure what the carbanion intermediate would look like and then what the curved arrows would be to convert it to its final oxanion form4. In base-catalyzed halogenation of acetone, how do you explain why the second (and third) halogenation occurs on the same carbon but not on the carbon in the other methyl group?5. Each of the following may participate in an elimination reaction, under the proper conditions. (a) Circle the alpha (a) carbon. (b) Circle the beta (B) carbon(s). (c) Draw the alkene product(s) that may form, with the new double bond between the a and B positions. (d) If more than one alkene product is possible, circle the most stable (Zaitsev) product.

- Which stetement is true about the following reaction? POCH3 + O A curved reaction arrow would start from the O in "OCH3. O A curved reaction arrow would start from the O in C-O. O OCH3 is a leaving group. O O is the nucleophile. OO OCH325) Draw all likely alkene products in the following reaction and circle the product you expect to predominate. Br NaOH acetoneIn the box, provide structure of the product for each transformation reaction.
- The major product of the given reaction has the molecular formula CH03. Draw its structure in the most stable tautomeric form. Select Draw Rings More Erase H 1. NaOCH,CH3 2. H3O* CH;CH2OHe 2. Draw the structures and explain why CH3CH₂O and CH3CO₂ are good nucleophiles but CH3SO3, water, and alcohols (R-OH) are poor nucleophiles. Propose a 'cutoff for the amount of negative charge needed to be a good nucleophile. CH3CH₂O CH3CO₂ CH3SO3 H₂O CH3OHDo hydration reactions like this one have Markovnikov and anti-Markovnikov products? I know that for addition of halides on alkene double bonds, there are Markovnikov products becasue of 1,2-halide/methyl shifts, but there usually aren't shifts in hydration reactions. Essentially, would the Markovnikov/major product for this reaction have a hydroxy group attached to the tertiary carbocation and the anti-Markovnikov/minor product for this reaction have a hydroxy group attached to the adjacent secondary carbocation?
