All right guys. So we're gonna attempt to do that last hydrogenation question that was left on the bottom of the page. So here it says, determine the major product. So this one here has one hydrogen directly connected to it. This one has none connected to it. The one with more will gain hydrogens. How many will it gain? We're using two moles of H pr. So it's gonna gain two hydrogens. This one here is gonna gain two halogens. Now we drew this CH three this way because it's the carbon that's connected to that carbon, but you could still draw it as CH three if you want. OK. So now that triple bonded carbon is no longer triple bonded because we're adding things, we're removing pi bonds. It's gonna gain two halogens because we're using two moles and then the other triple bonded carbon is no longer triple bonded, either it had one H to begin with and now it's gaining two more to become CH three. So what we make here at the end is a dye ha we get two halogens added on there. So it's a dial and they are on the same carbon when they're on the same carbon, we call it a Gemini geno dial. So think of uh astrology, Geminis twins and stuff like that. So Gemini means on the same carbon, what's on the same carbon two halogens? So remember we saw the dials earlier where two halogens are on neighboring carbons. And now, Gemini they're both on the same carbon. But here again, we're using our Carboni costal and again, we have a triple bond now, so that means we can add more than one mole of H pr. In this case, we chose to use two moles to get it all the way down to single bonds.
