WebMay 15, 2024 · Explanation: By looking at molecular structures a chiral compound has a C atom with 4 different atoms or group attached. If it does not have this it is achiral. By … WebRecall that a chiral center in a molecule, such as in (R)-2-butanol, is a tetrahedral atom with four different substituents.Some molecules, such as butane-2,3-diol, have multiple chiral centers. While molecules with only one chiral center are always chiral, molecules with multiple chiral centers may have achiral configurations.
