Vedclass · Answer

(A) For a monosaccharide to be correlated to $D$-glyceraldehyde,the $-OH$ group on the lowest chiral carbon (the chiral carbon farthest from the carbonyl group) must be on the right-hand side in the Fischer projection.Looking at the structures provided in the solution image:In structure $(A)$,the $-OH$ group on the lowest chiral carbon is on the right.In structure $(B)$,the $-OH$ group on the lowest chiral carbon is on the right.In structure $(C)$,the $-OH$ group on the lowest chiral carbon is on the left ($L$-configuration).In structure $(D)$,the $-OH$ group on the lowest chiral carbon is on the right.Thus,structures $(A)$,$(B)$,and $(D)$ have the $D$-configuration.The total number of such structures is $3$.

Identify the number of structures from the following which can be correlated to $D$-glyceraldehyde.
