Notice that two of the groups attached to the chiral centre are part of the same ring structure. WebPolymers are disclosed that are useful in performing chiral separations. A synthetic scheme for producing the novel polymers is also disclosed. The alkyl side chains of poly(.gamma.-alkyl-.alpha.,L-glutamates) have been altered, allowing the facile substitution of the side chains with pendent functional groups. The compounds may be used as a ...

They are very alike and share many properties in common, such as the same b.p., m.p., density, color, and solubility. In fact, the pair of enantiomers have the same physical properties, except the way they interact with plane-polarized light. michael hinson

WebA molecule which has no plane of symmetry is described as chiral. The carbon atom with the four different groups attached which causes this lack of symmetry is described as a chiral centre or as an asymmetric carbon atom. The molecule on the left above (with a plane of symmetry) is described as achiral. Only chiral molecules have optical isomers.
