Fischer projection is a method of representing the three-dimensional structures of molecules in two-dimensional form on a page. By convention, horizontal lines represent bonds projecting from the plane of paper towards the viewer and vertical lines represent bonds projecting away from the viewer. Absolute configuration is the arrangement of atoms or group of atoms that are independent of any other atom or group of atoms in the molecule. Chiral centers are designated as 鈥�搁鈥�or 鈥沦鈥�.

In part (a), the molecule is chiral and have 鈥湼殁�� configuration.

In part (b), the molecule is not chiral as it has no chiral centre present, thus, no configuration can be assigned.
