To determine: The structure of
Interpretation: The structure of
Concept introduction: The species that are asymmetric in nature have a tendency to rotate plane of polarized light and is thus optically active in nature.
(c)
To determine: The structure of given aldohexose X.
Interpretation: The structure of given aldohexose X is to be stated.
Concept introduction: The species that are asymmetric in nature have a tendency to rotate plane of polarized light and is thus optically active in nature.
(d)
To determine: If the given information contradicts the principle that optically inactive reagents cannot form optically active products.
Interpretation: The validation of the statement that optically inactive reagents cannot form optically active products for the given information is to be stated.
Concept introduction: The species that are asymmetric in nature have a tendency to rotate plane of polarized light and is thus optically active in nature.
