The given monosaccharidecan exist as aldohexose in its D-configuration. What is the total number of stereoisomers which can exist in pyranose form ?

Answer»

Solution :The pyranose form of the stereoisomers having D-configuration is shown :

There are three chiral `(C^(**))` ATOMS. THEREFORE, chiral centres = 3.
Total number of stereoisomers `= 2^(n)=2^(3)=8`.
