Question: Which of the following reactions can be used to convert an alkyne to an alkene?

Options:

Correct Answer: Hydrogenation

Solution:

Hydrogenation of an alkyne will add hydrogen across the triple bond, converting it to an alkene.

Which of the following reactions can be used to convert an alkyne to an alkene?

Which of the following reactions can be used to convert an alkyne to an alkene?

Step 1: Identify the alkyne you want to convert. An alkyne has a triple bond between two carbon atoms.
Step 2: Prepare for hydrogenation, which is the process of adding hydrogen (H2) to the alkyne.
Step 3: Use a catalyst, such as palladium (Pd), platinum (Pt), or nickel (Ni), to help the reaction occur.
Step 4: Add hydrogen gas (H2) to the alkyne in the presence of the catalyst.
Step 5: The hydrogen will break the triple bond and form a double bond, converting the alkyne into an alkene.
