a) Interpretation: The product expected during hydration of 4-octyne is to be given. Concept introduction: Addition of water to triple bonds occurs following Markovnikov regiochemistry to yield an enol as the product. The enol tautomerizes to give a ketone as the final product. Terminal alkenes and symmetrically substituted internal alkynes yield only one product. Unsymmetrically substituted internal alkynes yield a mixture of ketones as product. To give: The product expected during hydration of 4-octyne.
