Q1 This question has two parts Part A and Part B. Part 1: Acetone can react with a base to give the enolate ion A, which can further react with another acetone molecule to give B. Upon quenching with water, B generates C, the final product of this reaction. :Base H20 A H3C H. H3C H. Acetone a) Draw the structure of A, B, and C b) Using curly arrows, draw the mechanism of the reaction between A and acetone to give compound B. What's the name of this reaction. - c) Draw the two resonance forms (A and D) of the enolate (A) generated by the deprotonation of the a-carbon on acetone and show the interconversion between the two using curly arrows: I Base H3C H A D H Acetone d) Knowing that the pka of the a-proton on acetone is 19, choose amongst the following bases those who will be able to remove the proton, given the pKa of their corresponding conjugated acids.
