To identify the reagents used for the given set of reactions. Concept introduction: Under acid catalyzed conditions the carbonyl group gets protonated and gives a resonance stabilized intermediate resulting in formation of enol by deprotonation. The enol undergoes bromination to give an α -bromoketone or α -bromoaldehyde (acid-catalyzed halogenation) which then undergoes E2 elimination when treated with pyridine to form α , β − unsaturated ketone and α , β − unsaturated aldehyde respectively depending upon the starting material taken.

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.
