Questions & Step-by-Step Solutions
What is the product of the reaction of 2-pentyne with water in the presence of sulfuric acid?
Step 1: Identify the starting material, which is 2-pentyne. It is an alkyne with a triple bond between the second and third carbon atoms.
Step 2: Understand that the reaction involves adding water (hydration) to the alkyne in the presence of sulfuric acid, which acts as a catalyst.
Step 3: Recognize that during the reaction, the triple bond in 2-pentyne will break and a water molecule will add across the double bond.
Step 4: Determine the position where the water adds. In this case, the addition occurs in such a way that the resulting alcohol will have the hydroxyl (OH) group on the third carbon.
Step 5: Conclude that the product of this reaction is 3-pentanol, which is an alcohol.
