Definitions:

Fischer Projection

A method of drawing organic molecules to represent three-dimensional structures in two dimensions, showing configurations around chiral centers without requiring wedges or dashes for bonds.

(S)-2-bromobutane

A chiral compound characterized by its specific three-dimensional arrangement, with the bromine atom on the second carbon in its structure.

Enantiomer

One of two stereoisomers that are mirror images of each other but cannot be superimposed, usually differing in optical activity.

Asymmetric Carbon

A carbon atom bonded to four different atoms or groups, thus making it a chiral center.
