Can achiral molecules have stereoisomers
WebTherefore it is impossible to tell a racemic mixture apart from an achiral substance using polarimetry alone. Note that the terms chiral and optically active should not be confused. It would be incorrect to say that a racemic … WebThere are eight stereoisomers of 2,3,4,5-tetrahydroxypentanal, a group of compounds referred to as the aldopentoses.

Can achiral molecules have stereoisomers
Did you know?
WebHowever, some achiral molecules do have stereoisomers. This may seem surprising since chirality seems so closely tied to stereoisomerism. Consider however the "cis" and "trans" isomers of 1,4-dimethylcyclohexane shown below (Figure 3.5). Both molecules are achiral and neither has an enantiomer since both are identical to their mirror image. WebDiastereomers Molecules with more than one stereocenter have many different isomers. Say we have two stereocenters. Then the possible stereoisomers are RR, RS, SR, and …
