Question:

Hydrogenation of 3-carene is, in principle, capable of yielding two stereoisomeric products.
Write their structures. Only one of them was actually obtained on catalytic hydrogenation over platinum. Which one do you think is formed? Explain your reasoning with the aid of a drawing or a molecular model.
