Consider the following crossed aldol condensation. Which statement explains why a single cross condensation product is formed? 2,2-dimethylcyclohexanone "CH₃ H₂C, CH, H NaOCH.CH H3C thanol benzaldehyde 2,2-Dimethylcyclohexanone has only one alpha carbon which can form an enolate. Benzaldehyde has no hydrogens attached to the alpha carbon which eliminates the self-condenstation reaction. 2,2-Dimethylcyclohexanone is sterically hindered which limits the self-condenstation reaction. All of the above

Which of the following statements about the Aldol reaction is correct. Select all that apply. The aldol condensation reaction requires only a catalytic amount of base to form the a, -unsaturated carbonyl product In an Aldol reaction, the enolate is the electrophile that reacts with a neutral carbonyl nucleophile. Reacting 1 equivalent of LDA (lithium diisopropylamide) with 3-pentanone, the enolate will be formed quantitatively. Two equivalents of a ketone can be reacted with NaOH to form a B-hydroxycarbonyl product. Aldol...

Product was formed successfully based on the exp. below (about
85% yield), please interpret/discuss HNMR/IR in as much detail as
possible and assign peaks on HNMR (which peak represents which
protons of which group, etc). Note: I already know how you
determine the formation of the product so you can skip that part of
part b).
