What is the aldol condensation product of cyclohexanone as the ketone and benzaldehyde as the aldehyde? Show the MECHANISM, REACTION, and provide NAME of product.
Match the starting ketone or aldehyde with appropriate product of either aldol addition or adol condensation reaction. A ketone or an aldehyde from the list undergo either aldol addition (in a case aldol addition product can not undergo further elimination) or aldol condensation reaction in protic solvent under basic catalysis. Match the starting ketone or aldehyde with appropriate product of either aldol addition or aldol condensation reaction propanal acetaldehyde 2-ethyl-2-hydroxy-hexanal 2-methylbuta ethanal Please answer 2-ethyl-4-methyl 2-hexenal Choose 2-methyl-2-pentenal 2-ethyl-3-hydroxy-2,4-dimethyl hexanal...
