Vedclass · Answer

(D) The $D$ or $L$ configuration of a monosaccharide is determined by the position of the $-OH$ group on the chiral carbon furthest from the carbonyl group (the $C_5$ carbon in fructose).If the $-OH$ group is on the right side,it is the $D$-isomer.If the $-OH$ group is on the left side,it is the $L$-isomer.Structure $II$ represents $D$-fructose because the $-OH$ group at $C_5$ is on the right.Structure $IV$ represents $L$-fructose because the $-OH$ group at $C_5$ is on the left.Therefore,the pair representing $D$-fructose and $L$-fructose is $II$ and $IV$.

Consider the following structures. Which of the pairs represent $D$-fructose and $L$-fructose,respectively?
