Eventually, we will be able to mentally conversion between these two structures. The stereochemical formula for (R)-lactic acid can be drawn using either method. To build this skill, we begin by drawing the structures and converting them step wise. Models can also be helpful. Eventually, we will be able to mentally conversion between these two structures. The correct Fischer projection formula of (2 R, 3 S) − 2, 3 − dihydroxy butanoic acid is : BeCi2. AB2 --- has no unshared pairs --- linear.

Despite what one may perceive from a printed page or even the computer screen you are now looking at, most molecules are not 2D objects, they are 3D as a result of the spatial arrangement of the atoms, groups and bonds. Here you will find a brief introduction to the R,S designations of configuration of stereogenic centers.
