Show the ketone that forms when each alkyne undergoes an oxymercuration reaction.

(a) 5-methylhept-1-yne

(b) 1,8-dicyclopentyloct-4-yne

Acid-catalyzed hydration of alkynes in the presence of HgSO₄ produces ketones as products. Identify one possible alkyne which deviates from this rule and produces an aldehyde instead.

Oxymercuration-reduction is an excellent method for obtaining single compounds from the hydration of symmetrical internal or terminal alkynes. Draw the products of the oxymercuration-reduction reaction for the following compound:

2-pentyne

Provide the best alkyne to use to produce each of the following ketones.

Propose a way to synthesize the product shown using the provided starting molecule, any inorganic reagents, and any organic molecule with only 4 carbons or fewer.

Hydration of an asymmetrical internal alkyne via oxymercuration gives two different compounds. Predict the products that could form from the hydration of the alkyne below.
