Concept explainers
(a)
Interpretation: The most stable arrangement of substituents on the six-membered ring by using chair form is to be drawn.
Concept introduction: Glucose is a monosaccharide. It is made by the plants during the process of photosynthesis. The molecular formula of glucose is
(b)
Interpretation: The chair form of glucose is to be converted into wedge-dash representation.
Concept introduction: Glucose is a monosaccharide. It is a simple sugar that is made by the plants during the process of photosynthesis. The molecular formula of glucose is
(c)
Interpretation: A constitutional isomer of glucose is to be drawn.
Concept introduction: Constitutional isomers have same molecular formula but the connectivity of the atoms is different.
(d)
Interpretation: The stereoisomer of glucose that has an axial OH group on one carbon is to be drawn.
Concept introduction: The two stereoisomers of glucose are
