All right. Hi, everyone. So let's consider the molecule solo. The question says to classify the molecule as an acetyl or Kau and provide the aldehyde or ketone that produced the molecule. So recall first and foremost that aces and ketones are the protecting groups of aldehydes and ketones respectively. So what both the acetyl and the kel have in common is that they're carbonel or in other words, their carbon double bonded to an oxygen is replaced, buy two our coxie groups. So on the car bono carbon, we're going to instead have two bonds to oxygen and then those oxygen atoms are connecting to other all kill groups. And we can see that in the structure provided because notice how there is one carbon atom in the structure here that is connecting to two oxygen atoms, each of which has its own a group associated to it. But the difference between an acetyl and a ketone is the same difference between an aldehyde and a ketone. Recall that a ketone has two R groups on either side of the car bal, whereas all the hides only have one R group and at least one hydrogen atom. So that distinction right? There is what allows us to determine whether or not this compound is an acetyl or a ketone. Now remember that there is such a thing as a hem asa or a hemi Kau where instead of having two oxy groups on the same carbon, we have only one oxy group and one hydroxy or oh group. Now, if I focus my attention on the one carbon atom that is connecting both of the al Coxie groups here, this carbon is connecting to two other carbon atoms or two our groups. And recall that the ketone is the functional group with two R groups on either side of the car bal. So all this is to say that the compound in question is a key out. The molecule is a ketone because it is produced from a ketone. So in this case, the carbon atom that is connecting the oxy groups is going to be the car bono carbon. So if I incorporate the two R groups on either side, I can see that I have a 12, five carbon chain. So that's the first thing I will draw here. I have a five carbon chain and the car bono is on carbon two of the chain itself. So when it comes to the formation of an ace or a ketone, you can imagine that the car bal of the aldehyde or the ketone is essentially split into a V with an oxygen on either end and So in this case, just to open up some space here for the answer, right, the molecule in question is Akita because in addition to the two all coxie groups on the same carbon, there are two R groups on either side of that particular carbon app and there you have it. So here the molecule is a Quito and here is the ketone that produced the molecule in question. And so with that being said, thank you so very much for watching. And I hope you found this helpful.
