Textbook Question
Chapter 15.5, Problem 11P
Is the following statement true or false?
If the newly added group in the tetrahedral intermediate is a stronger base than the group attached to the acyl group in the reactant, then formation of the tetrahedral intermediate is the rate-limiting step of a nucleophilic acyl substitution reaction.

During the decarboxylation of acetoacetate, what is the nucleophile and what is the electrophile? Is the formation of a schiff base simply a preparation step or is the formation of a schiff base formed also by nucleophile/electrophile interaction?
What is difference between the acetoacetic and malonic ester syntheses? Provide an example of each, including all intermediates..
1. Put these three common types of carbonyl compound in order of decreasing reactivity
ester amide acid chloride
2. For the least reactive, show the interconversion to its other resonance form: How does this electron delocalisation make it stable?
3. For the most reactive, draw the mechanism of its undergoing hydrolysis (reaction with H2O):
Why makes this type of carbonyl so reactive to nucleophiles?
