The synthesis of each of the given product from butanal is to be shown. Concept Introduction: In aldol addition and aldol condensation, a C − C bond formation takes place. Aldol condensation occurs in a protic solvent in the presence of a base. Inacid catalysis, the direct dehydration of the aldol intermediate leads to the formation of the α , β − unsaturated product. LiAlH 4 reduces the carbonyl groups of aldehyde and ketone , whereas NaBH 4 reduces the carbon-carbon double bond.

Answer 1

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.
