b)
Interpretation:
How to convert 1-butyne in to butanal is to be shown.
Concept introduction:
Terminal alkynes when hydrated using hydroboration-oxidation reaction yield an enol with OH group attached to the terminal carbon as the reaction follows anti-Markovnikov regiochemistry. The enol obtained then tautomerizes to an
