Solution
Solution Steps
Step 1: Identify the molecule
The given molecule has a double bond, indicating it is an alkene. Counting the carbons, we find there are five carbons in the longest chain. A methyl group is attached to the second carbon. Thus, the molecule is 2-methylpent-2-ene.
Step 2: Hydrogenation reaction
Hydrogenation is an addition reaction where hydrogen adds across a double bond, converting an alkene to an alkane. In this case, 2-methylpent-2-ene reacts with H₂ in the presence of a Pt/Pd catalyst to form 2-methylpentane.
Step 3: Product
The product of the hydrogenation of 2-methylpent-2-ene is 2-methylpentane.
