Question
Which of the following is false?Select answer from the options belowIn the acid-catalyzed hydration of alkynes, an enol intermediate is formed.Acid-catalyzed hydration of terminal alkynes affords anti-Markovnikov products.Hydration of alkynes with H3O+ typically requires a mercury catalyst.Acid-catalyzed hydration of terminal alkynes affords ketone products.
Solution
The false statement is: "Acid-catalyzed hydration of terminal alkynes affords anti-Markovnikov products."
In acid-catalyzed hydration of terminal alkynes, the reaction follows Markovnikov's rule, not anti-Markovnikov. This means that the hydrogen (H) atom of the water molecule will add to the carbon atom of the alkyne that has more hydrogen atoms, and the hydroxyl group (OH) will add to the other carbon atom. This results in a ketone product, not an anti-Markovnikov product.
