Multiple Choice

Which TWO of the following traits apply to Fischer's Convention for naming stereoisomers?

Utilizes (+) and (-) designations.

Utilizes (D) and (L) designations.

Verified step by step guidance

Understand that Fischer's Convention is a method used to designate the configuration of stereoisomers, particularly carbohydrates.

Recognize that Fischer's Convention utilizes (D) and (L) designations, which are based on the orientation of the hydroxyl group on the chiral center farthest from the aldehyde or ketone group in a carbohydrate.

Note that Fischer's Convention requires drawing the compound with the aldehyde or ketone group at the top of the Fischer projection, which is a two-dimensional representation of a three-dimensional molecule.

Identify that Fischer's Convention does not use (+) and (-) designations, which are related to optical activity, nor does it use (R) and (S) designations, which are part of the Cahn-Ingold-Prelog system for naming stereochemistry.

Understand that Fischer's Convention is not based on the optical properties of the compound in solution, but rather on the spatial arrangement of atoms in the molecule.
