Name each alkyne. d.

Hey, everyone were asked which of the following is the correct name for the Alkaline 1st. Let's go ahead and determine our longest carbon chain. So counting this out, we have and eight. So we have an eight carbon chain. So we can go ahead and eliminate A and B. Already. Since this tells us that we have a five carbon chain due to that prefix of pent. Now let's go ahead and determine where our triple bond is located. As we can see right here. Our triple bond is at carbon number four. So C and D. Still stand. Now, if we had reversed this and counted it out in a reverse way such as and eight, we would still have that triple bond located at carbon number four. So the triple bond, no matter which way we counted it out. Is that carbon number four. Now let's go ahead and look at our substitute prints. So looking at our carbon number three, we have a metal substitue in And looking at carbon # six. We also have a method substitue in. So it looks like C is going to be our answer since this tells us that we have two metals on carbons three and six. Now, I hope that made sense. And let us know if you have any questions
