Question: Which of the following is the correct mechanism for the hydrogenation of an alkene?

Options:

Correct Answer: Electrophilic addition

Solution:

The hydrogenation of an alkene involves the addition of hydrogen across the double bond, which is an electrophilic addition mechanism.

Which of the following is the correct mechanism for the hydrogenation of an alkene?

Which of the following is the correct mechanism for the hydrogenation of an alkene?

Step 1: Identify the alkene, which has a double bond between two carbon atoms.
Step 2: Understand that hydrogenation means adding hydrogen (H2) to the alkene.
Step 3: Recognize that the double bond in the alkene is reactive and can break to allow hydrogen to attach.
Step 4: Know that this process is called electrophilic addition, where the double bond acts as a nucleophile and reacts with the electrophilic hydrogen.
Step 5: Visualize the addition of hydrogen atoms to the carbon atoms that were previously involved in the double bond, resulting in a saturated alkane.
