QUESTION 12 Consider the following crossed aldol condensation. Which statement explains why a single cross condensation product is formed? 2,2-dimethylcyclohexanone 0 H₂C H₂C H NOCH₂CH₂ ethanol CH₂ CH₂ benzaldehyde O 2.2-Dimethylcyclohexanone has only one alpha carbon which can form an enolate. O Benzaldehyde has no hydrogens attached to the alpha carbon which eliminates the self-condenatation reaction. O 22-Dimethylcyclohexanone is sterically hindered which limits the self-condenstation reaction. All of the above.
