Which of the following results in a single ketone product following acid catalyzed hydration?
Which of the following results in a single ketone product following acid catalyzed hydration?
During acid catalyzed hydration, a hydroxy group replaces one of the bonds in the triple bond and a double bond is formed. This is called an enol. The enol naturally turns into a ketone in a process called tautomerization. The hydroxy group can attach to either carbon across the double bond, and naming is done so that substituents have the lowest numbers. Only on 5-decyne will result in a single product, as no matter which carbon the hydroxy group bonds to, it is still on carbon 5. Thus, the only final product is 5-decone.
The other answer options will still react, but will form multiple products due to lack of symmetry.
