(i) For the five Brnsted acids illustrated below, identify the most acidic protons and explain the order of acidity observed. (Your answer should include structures of the species involved in their acid/base equilibria and resonance structures to illustrate any key inductive and resonance effects.) [10] (ii) Suggest reagents and reaction conditions, suitable for converting compound A below, into compounds B and C and explain your choices. (You should include reaction mechanisms, if they help with your explanations.) A (i) Ethyl acetoacetate D is a versatile reagent for the synthesis of a wide range of ketones. Suggest reagents and conditions which could be used to convert D into E and F. [7] [8] (ii) Explain your chosen synthetic route to compound E with the aid of reaction mechanisms. [8] (i) Compound G shown below, has been isolated from the distillate of the oil obtained from pressed Valencia oranges and it can be produced synthetically, by the reaction shown. Explain this reaction with the aid of a mechanism
