Prochiral molecules are generally represented as Pro-R or Pro-S, and these are the precursors of chiral molecules which can be converted into chiral molecule from Prochiral in a single step. Prochirality can be observed in organic compounds in two ways, one way is the conversion of sp2 carbon into a chiral sp3 carbon via a reaction, and the other way is via substitution of a Prochiral substituent (usually hydrogen) with another substituent that results in a chiral center.
