WebThe general formula for determining the maximum number of stereoisomers of a molecule is 2 n, where n is the number of chiral centers present in the molecule. IN the case of glucose, carbons 2, 3, 4, and 5 are chiral centers. Therefore, there are 2 4 = 2 x 2 x 2 x 2 = 16 stereoisomers of the molecule. WebLets look at the Chiral C2. The reason The surrounding Carbon (C1, C3) are considered different is because of what each C is attached to. C1 and C3 are attached to a whole string of carbons (arms). Both of these arms are different For the example of glucose. C1 could be COH while C3 is C4H5 (OH)4.
