Interpretation:
Whether the given compound,
Concept introduction:
A carbon atom that has four non-equivalent atoms or groups attached to it is known as chiral carbon atom. Chiral carbon centers are also called as asymmetric or stereogenic centers. In stereocenters, the interchange of groups forms another stereoisomer. A chiral compound is able to move the plane polarized light is known to be optically active compound.

- One of the following molecules (a)–(d) is d-erythrose 4-phosphate, an intermediate in the Calvin photosynthetic cycle by which plants incorporate CO2 into carbohydrates. If d-erythrose 4-phosphate has R stereochemistry at both chirality centers, which of the structures is it? Which of the remaining three structures is the enantiomer of d-erythrose 4-phosphate, and which are diastereomers?arrow_forwardDoes the molecule below exist as a pair of enantiomers? If so, change the bonds to wedges and dashes to reflect R stereochemistry. If the molecule does not exist as a pair of enantiomers, check the box below.
