The product of the reaction in which propanal is added slowly to a basic solution of formaldehyde is to be predicted. Concept introduction: This is a crossed aldol reaction. When two different aldehydes , each having alpha hydrogen, are reacted with each other, they can form more than one product. When one of the aldehyde used does not have alpha hydrogen, and another is added slowly, the number of the product can be reduced to one.

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
