WebJul 20, 2024 · A and B are both chiral molecules, and they are enantiomers of each other. 2-propanol, unlike 2-butanol, is not a chiral molecule. Carbon #2 is bonded to two identical substituents (methyl groups), and so it is … WebLook again at the carbon atoms that Sal identified as chiral atoms. There are four different substituents/groups attached to those atoms, which is why those are both chiral atoms. But, he shows that when the molecule is rotated, it is still the same molecule. That's why even with the chiral ATOMS, the molecule itself is achiral.

WebThe chirality of the molecule results from the structure of the central carbon. When the central carbon is sp3 carbon and bonded with four different groups (represented by four different colors in the model), the molecule is chiral. The central carbon is called the chirality center (or asymmetric center). WebDefinition. The chirality of a molecule is based on the molecular symmetry of its conformations.
