Identify the number of structure/s from the following which can be correlated to .
- a
one
- b
two
- c
four
- d✓
three
three
Step 1: D-Glyceraldehyde Standard — In the Fischer projection of , the group on the chiral center is situated on the right side.
Step 2: Correlating Structures — We analyze the given structures by rotating them to match the standard Fischer projection orientation or by determining their R/S configurations.
Step 3: Count — Three of the provided representations can be correctly correlated to the D-configuration of glyceraldehyde through allowed rotations.
Key Point: A rotation in the plane of paper maintains the configuration, while a rotation inverts it.
