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.

Consider this step in a radical reaction: Y What type of step is this? Check all that apply. Draw the products of the step on the right-hand side of the drawing area below. If more than one set of products is possible, draw any set. Also, draw the mechanism arrows on the left-hand side of the drawing area to show how this happens. ionization propagation initialization passivation none of the above
