Chapter 59, Problem 8Q

can someone please help show and explain the mechanism with 3-nonenoic acid to y-nonanoic lactone?

Can you please answer all of these questions And for the last question after performing 3 extractions, you do TLC on them and get the following result, what can you tell about your product?

2. With an example describe mechanistically how an extraction is carried out acid-base.

Why is it difficult to stop the reaction at the mono-brominated stage?

Draw resonance structures of anisole or the intermediate in the above reaction to demonstrate why the methoxy group is an o,p-director

1) Based on the Material Safety Data Sheets (MSDS) for the compounds, which of the compounds in this experiment is the most hazardous, and why (you have been given a representative aryl halide rather than all of the alkenes – as the products are all new, there’s not a simple answer to gauge their potential hazard)?  2,3-dihydrofuran,2-Mercaptobenzimidazole,Selectfluor, Dimethylformamide,dichloromethane-methylene chloride.

Explain the features of E1 reactions are worthy of note ?

Would NaBh4 work as a reagent for this reaction as well?

Based on the procedure given below, answer the following questions about the aldolcondensation reaction:"In a clean 50 mL Erlenmeyer flask, add the ketone (0.5 g),aldehyde (2.0 mL), 95% ethanol (10 mL), and 2N aqueous sodium hydroxide.'Assume the aldehyde and ketone are the answers you provided in Question 9. (4-methoxybenzaldehyde, MW = 136.148 and cyclohexanone MW = 98.143) a. Determine the limiting reagent for the above reaction. Only perform calculations on theorganic reactants. Write out all calculations
