R, S-configuration is a useful tool for determination of enantiomers, diastereomers and homomers. If configuration of all chiral centres are opposite then structures are enantiomers, if all chiral centers have same configuration then they are homomers and if some have same configuration and some have opposite configuration then they are diastereomers.

Among above structures find out diastereomeric structures:

A

II and III

B

Optical rotations of some compounds along with their structures are given below. Which of them have D configuration?

Monosaccharides containing an aldehyde group are called aldoses while those containing aketo group are called ketoses. The aldehyde group is always present at C_1 while the keto group is usually present at C_2 . All monosaccharides containing five and six carbon atoms have cyclic structures, furnaose (five membered) and pyranose (six membered). During ring formation, C_1 in aldoses and C_2 in ketoses becomes chiral and hence all these monosaccharides exist in two stereoisomeric forms called the alpha -anomer and the beta -anomer while C_1 and C_2 are called glycosidic or anomeric carbon atoms. In contrast, stereoisomers, which differ in configuration at any other chiral carbon other than the glycosidic carbon are called epimers. Two molecules of the same or different monosaccharides combine together through glycosidic linkage to form disaccharides. All monosaccharides (aldoses and ketoses) and most disaccharides reduce Tollens'reagent and Fehling's solution, undergo mutarotation and form osazones. Which of the following pairs give the same osazone?
