a) Interpretation: Starting from which alkyne the compound shown can be prepared is to be stated. Concept introduction: Carbonyl compounds can be obtained by the tautomerization of enols produced when alkynes are hydrated. The hydration of terminal alkynes can yield an enol which can tautomerize to an aldehyde or a ketone . If oxymercuration–demercuration hydration process is used, the OH adds to the more highly substituted carbon in the triple bond following Markovnokov regiochemistry. If hydroboration –oxidation process is used, the OH adds to the less highly substituted carbon in the triple bond following anti-Markovnokov regiochemistry. To state: Starting from which alkyne the compound shown can be prepared.

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.
