Draw the ketone that is expected to be formed when the alkyne shown below undergoes the hydroboration-oxidation reaction.

What product is formed in a reaction of the given alkyne with Sia₂BH in THF followed by H₂O₂, NaOH, H₂O?

What is the product of the given reaction?

Determine the major product formed when 3-hexyne reacts with R₂BH in THF, followed by H₂O₂, OH⁻, and H₂O.

Hydroboration-oxidation of internal alkynes produces ketones while the same reaction for terminal alkynes produces aldehydes. Draw the final products when 1-cyclohexyl-1-propyne is subjected to hydroboration-oxidation. Describe why hydroboration-oxidation of an unsymmetrical internal alkyne results in a mixture of products.

For the compound shown below, predict products that result when it undergoes the following:

a. Acid-catalyzed hydration
b. Hydroboration-Oxidation
