Question

of each other. 36.) Glucose and galactose are A) anomers B) enantiomers C) epimers D) cis-trans isomers of D-glucose. 37.) D-galactose and D-talose are A) diastereomers B) epimers C) enantiomers D) cis-trans isomers

Answer 1

Ans.36 Epimer are the stereoisomers ,which contains more than one chiral center but only differ in configuration at one chiral center. So glucose and galactose are C_{​​​​​​4} epimers . Which are shown in image. Ans. 37 D- galactose and D- talose are diastereomers of glucose because epimers are the stereoisomers which are not mirror image to each other .So, these are also termed as diastereomers.
