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.
