WebStereoisomers having instability at a stereogenic center can react to produce stereochemically modified forms. 15–18 This can be triggered by an adjacent group that decreases stability at the chiral center. 15 An enantiomer can irreversibly ‘racemize’ and reach the racemic mixture at equilibrium. It can also ‘enantiomerize,’ or reversibly … Web1. Define and understand the concepts of chirality and enantiomers 2. Identify centres of chirality in organic molecules 3.
