Q
Q: Which of the following is the correct mechanism for the hydrogenation of an alkene?
Solution: The hydrogenation of an alkene involves the addition of hydrogen across the double bond, which is an electrophilic addition mechanism.
Steps: 5
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.
