 What are we going to get as a product from this reaction before, or just as a product? Let's not do any mechanism or anything like that. Just name the product. Pintain. Pintain? Okay, so let's count. One, two, three, four, five, right? And what did we say when we have platinum and hydrogen? What is it going to do to these outcomes? Hydrogenate. Hydrogenate. Hydrogenate. And is it going to be able to hydrogenate to just the alkene? No, so it goes all the way to the alkane, right? So since we have five carbons here, you guys are absolutely right. It'll make pentane, okay? Could you guys predict another molecule that would make pentane that maybe is an alkyne? You make a terminal. Yeah, so if we made this, so I'm going to erase this one and just give you another example. Would that make pentane? Yeah. Of course, we could have moved that triple bond to the other carbon in between the other two carbons. Would you also make that transduce by putting it on the second carbon? Yeah, so we could have had an alkene near second. Yeah, so there would be some other ones that we could do, of course. So that's what I was saying. We could move that double bond around. We could have something like that. We could have something like that. All of those would give that same product. So, any questions on this one?
