Hey, guys, let's take a look at the following new video dealing with hydrogenation. So here hydrogenation can be seen as a reduction reaction in which two hydrogen are added to one pi bon. So here the ratio is you need one mole of BR to not be are two of H two to reduce one pi bon. Now here. Let's talk about this word. Reduce and reduction in Gen. Cam and General Chemistry, we said reduction refers to gaining electrons, but in organic chemistry, we don't really say reduction means that specifically what we say in organic chemistry. We say reduction involves gaining off hydrogen ins. And the reason we say gaming of hydrogen instead is that the hydrogen is that we're gaining. Add electrons to something. Okay, so that's what we're saying. They don't physically add riel electrons. In a sense, what they're doing here is they're less electoral negative than the thing they're connected to. So they're gonna be sharing their electron energy to that new compound. So on or go, we say reduction means adding hydrogen and jen can we say reduction means adding or gaining electrons. So knowing the difference between these two is key to getting the answer. Correct. So in this first example, what you guys to take a look just realize here, when it comes to hydrogenation, all we're gonna do is that hydrogen is to the double bond to remove the double bond. And remember what happens when we have Ah, hydrogen on a carbon and we have, ah, skeletal formula. Do we show them or not? Where did those hydrogen is go And are they visible? Knowing that is he key to getting this answer correct? So attempt to do this on your own and then come back and see a video of me explaining what the answer is.
