JEE MAIN Chemistry QUESTION #1012
Question 1
Identify the number of structures from the given Fisher projections that can be correlated to D-glyceraldehyde:
  • Four
  • One
  • Two
  • Three✔️
Correct Answer Explanation
D-glyceraldehyde has the \(-\text{OH}\) group on the right in Fischer projection at the chiral carbon nearest to the bottom. Checking each structure (A, B, C, D): those with appropriate configuration matching D-glyceraldehyde's stereochemistry — three of the four structures can be correlated.
