WebEthyne. Medium. Solution. Verified by Toppr. Correct option is A) Aklynes on hydration give ketones except ethyne that gives aldehyde. Hence, propyne give kethone. Video Explanation. Was this answer helpful? WebHydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
WebMercuric ion catalyzed hydration gives similar results. Hydroboration-Oxidation is a two step pathway used to produce alcohols. The reaction proceeds in an Anti-Markovnikov manner, where the hydrogen (from BH 3 or BHR 2 ) attaches to the more substituted carbon and the boron attaches to the least substituted carbon in the alkene bouble bond.
