The mercuric-ion-catalyzed hydration of a terminal alkyne would give _____. A) an alkenol B) a ketone...
Hydration of terminal alkynes in the presence of mercuric sulfate always yields a methyl ketone whereas hydration of internal alkynes produces mixture of ketones. Explain with appropriate example. Hydroboration-Oxidation of an internal alkyne produces ketone whereas the same reaction for a terminal alkyne yields aldehyde - why? State the rule associated in it.
