Emil Fischer arbitrarily established the D/L Relative Configuration system. Which specific molecule — Isomerism and Stereochemistry Chemistry Question

💡 Solution & Explanation

The D/L relative configuration system is deeply anchored to the arbitrary historical standard of (+)-Glyceraldehyde (2,3-dihydroxypropanal). In its standard vertical Fischer projection, if the defining hydroxyl ($-OH$) group on the chiral center is oriented on the right side, the molecule is assigned the 'D' configuration. If on the left, it is 'L'.
