All right. Hi everyone. So for this question, let's determine the product of the reaction shown below where an all kind react with hydrogen gas in the presence of a palladium catalyst. Now here on the screen are four different answer choices. So recall first and foremost that the reaction shown on the screen is an example of the hydrogenation of an all kind because we are adding hydrogen gas to an all kind in the presence of a palladium or metal catalyst. So with respect to finding the product of this reaction, recall that each of the carbons in the triple bond gained two hydrants, each. This means that our product is going to be an all can. Now, if we consider the condensed formula provided, then the two carbons of the keen, namely carbons, four and five of the parent chain are going to each receive two hydrogens. So instead of writing this triple bond in between them, I would write out the condensed structure and I would place or write both of them both carbons there sch twos and all other carbons are going to therefore remain the same. Meaning the less carbon here is going to have two methyl groups still. So after I check my number of carbons, I can see that carbons, three and four are now all cane carbons with two hydrogens each. So if I consider the answer choices first, I can eliminate option A because it shows an all keen instead of an all kin, right? There's a double bond in between two carbons here and the same is true for option D because option D also shows and all key. Now between options B and C, it boils down to how many carbons go before the two methyl groups recall that in our product, we have to have five carbons before we get to our two metal substituents. So if I count the number of carbons in Option B, here, I get that there are four before the metal groups, right? So that would be too little. And option C has exactly five carbons before the two methyl groups. So option C is going to be our answer, right? Because option C is our all cane product with the correct number of carbons and there you have it. So with that being said, thank you so very much for watching and I hope you found this helpful.
