@Brian_BH Could you share rationale for 402472 & 402756?
QID 402472:
Question requires being able to identify the anomeric carbon of a given molecule, in order to identify the appropriate substituents that are located on said carbon. The passage information states that it is the substituents on the anomeric carbon that are responsible for a particular shift in NMR, with the question asking to identify said carbon given a diagram of the molecule in question, necessitating the knowledge and ability to discern the anomeric carbon of a cyclic monosaccharide from the other carbons present.
QID 402756:
Question asks to determine whether two example molecules are anomers. This, by necessity, requires the understanding of the location and role of the anomeric carbon as well as being able to identify is in the given monosaccharides, in order to be able to determine if, indeed, the saccharides in question do differ at the anomeric carbon as would be necessary for their distinction as anomers specifically.
