Web9 jun. 2024 · There are six optical isomers of CH3(CHOH)3CH3. Explanation: The maximum number of optical isomers is 2n, where n is the number of chiral centres. The number is of course reduced if the molecules have an internal plane of symmetry. Here, n = 3, so 2n = 23 = 8. Webdrawing the first molecule as you have to distinguish which group goes where, but once you figure this out, the rest is easy! All you have to do is draw the mirror image and place a dashed line, to represent the mirror. Many α-amino acids (except glycine) have optical isomers in which the chiral carbon is attached to four different groups.
