HO HO MeO CO₂H D CO₂Me F CO₂Me gagg MeOH OH OH OMe C E G (a) What additional reagent, D, is required for the efficient Fischer esterification reaction, used to convert carboxylic acid, C, to ester, E? (2) (b) Give a curly arrow reaction mechanism to explain the conversion of carboxylic acid C into ester E. (10) (c) Suggest suitable reagents, F, for the Williamson ether synthesis of diether, G, from E. (3) (d) This particular transformation (E to G) is described as an SN2 reaction. Using this reaction explain the meaning of the term "SN2." (5) (e) Explain what is meant by the terms "electrophile" and "nucleophile." Provide an example of each to support your answer. (5)
