WebFeb 21, 2024 · The point that determines the presence or absence of chirality in a molecule is the chiral centre of that molecule. Chiral centre is a carbon atom of an organic compound that has four different substituents attached to it. Chiral compounds are the compounds containing chiral carbon atoms. Chirality is actually the property of having … WebMay 10, 2015 · 11. Look for carbons with four different groups attached to identify potential chiral centers. Draw your molecule with wedges and dashes and then draw a mirror image of the molecule. If the molecule in the mirror image is the same molecule, it is achiral. If they are different molecules, then it is chiral.
