(a)
Interpretation Introduction
Interpretation:
The structure of D-erythrose has to be identified from the given structures.
Concept introduction:
The configuration of stereoisomer is determined by Cahn-Ingold-Prelog system rules.
According to Cahn-Ingold-Prelog system,
The group attached to asymmetric center should be ranked based on the
For Fischer projection formula: Check the direction of arrow drawn in the direction of decreasing priority. If the arrow points clockwise direction, then the compound has R configuration. If the arrow points counterclockwise direction, then the compound has S configuration. If the group with lowest priority is bonded in horizontal line, then the configuration is assigned as just reverse.

Interpretation Introduction
Interpretation:
The structure of D-threose has to be identified from the given structures.
Concept introduction:
The configuration of stereoisomer is determined by Cahn-Ingold-Prelog system rules.
According to Cahn-Ingold-Prelog system,
The group attached to asymmetric center should be ranked based on the atomic number of atom which directly connected to asymmetric center. The higher the atomic number of atom, higher the priority. If there is tie, then consider the next atoms attached to the connected atom and so on.
For Fischer projection formula: Check the direction of arrow drawn in the direction of decreasing priority. If the arrow points clockwise direction, then the compound has R configuration. If the arrow points counterclockwise direction, then the compound has S configuration. If the group with lowest priority is bonded in horizontal line, then the configuration is assigned as just reverse.
