WebMar 9, 2015 · Prochirality and axial chirality. Prochirality is the idea that a set of achiral groups can give rise to chirality in a reaction. For instance, consider 2-butenone, an achiral molecule. The carbonyl “faces” are said to be enantiotopic. Next, consider propan-2-ol. It is achiral because its two methyl groups are equivalent.
