Question

Identify the functional group that would be expected to be found in the final product upon completion of the reaction between 1-hexyne and a mixture of mercuric sulfate and aqueous sulfuric acid. ketone carboxylic acid aldehyde diol ether

Answer 1

Answer:

Ketone.

Explanation:

Alkynes experience additions of water catalyzed by acids, across the triple bond in the presence of mercuric ion as a catalyst. Generally, a mixture of mercuric sulfate and aqueous sulfuric acid is used.

Under acidic conditions, mercury is replaced by hydrogen to form a vinyl alcohol, called enol.

Enoles tend to be unstable and isomerize in ketones. This quick equilibrium is known as the keto-enol tautomerism.
