Alright, guys. So let's attempt to do that hydrogenation question that was left. So here it says, determine the major product for the following hydrogenation reaction. So we're gonna basically add Ah, hydrogen to this double bonded carbon in this double bonded carbon and adding hydrogen gets rid of that double bond. So what you're gonna get here at the end would be this structure. So you literally just take off the double bond. And remember, we don't show the hydrogen is because in a skeletal formula, we're going to say here that hydrogen is connected to carbon are invisible, so the carbons are invisible and the hydrogen is connected to them are invisible, so that will be our answer there. Now, look at the trend. We used one mole to get rid of one double bond. So knowing that, try to answer the following question where I give you a structure and I'm asking how many moles of H two would be necessary to completely reduce the structure. So just recall what one mole of h two conduce you. How many pi bonds total do we have in this molecule? That is the answer. That's the key To answer this question correctly. Good luck, guys.
