Identify the following carbohydrates as the α or ß anomer:

(b)

Accepted Answer

Welcome back, everyone determine whether the carbohydrate shown below is an alpha or beta animal. Now to answer this problem, first of all, we have to label the carbon chain carbons 12345 and six. Our next step is to identify the anomic carbon which is bonded to oxygen, right? And essentially, that would be carbon number two. In our labeling system, it essentially has properties of Isabel. And because it is Aamer carbon, we have to identify if there's a hydroxyl group present, we call it the Aamer hydroxyl group. Our next step is to identify the C H2O H part from carbon number six. So we're going to label it and now we have two possibilities, an alpha or a beta anma, an alpha, an animal would have the oh on the anime carbon on the opposite side to the CH 20 add carbon six. What we notice however, is that the two substituents are on the same side relative to the plane of the ring, which corresponds to the beta animal. For the beta animal, we would have hydroxy on the same side. Yes, the C H2O H four carbon six. This is exactly what we have. As we can see, we have the plane of the ring and the two substituents are on the same side, meaning the answer to this problem would be beta and that's the final answer to this problem. Thank you for watching.
