The product that results when citronellal is treated with excess H 2 in the presence of a Pd catalyst should be determined. Concept Introduction: Hydrogenation is the reaction of alkenes or alkynes with hydrogen gas. This is an addition reaction. H 2 is added across the C-C double bonds of alkene, triple bonds of alkynes. But this reaction occurs only in the presence of a metal catalyst like palladium. In a reduction of an organic molecule, either the number of C-O bonds decreases or number of C-H bonds increases. So when an aldehyde is reduced by H 2 in the presence of Pd catalyst, C=O double bond is reduced to C-O single bond and H 2 is added across this C=O double bond forming a primary alcohol.

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.
