Chiral chemistry
WebThe term chiral, from the Greek work for ‘hand’, refers to anything which cannot be superimposed on its own mirror image. Your hands, of course, are chiral – you cannot superimpose your left hand on your right, … WebThe model illustrates that a chiral cavity can be used to selectively couple to molecules of a specific handedness and thus provides a means to discriminate enantiomers from a racemic via the versatile tool box of polaritonic chemistry and cavity QED. Such a chiral discriminating effect can be observed in all eigenstates of the strongly ...

WebFor example, these are the chirality centers in each of the following molecules: To recognize the chiral center, look for the wedge and dash bonds as usually, these are the ones indicating a chiral center. One important thing to remember, is a carbon with a double bond cannot be a chiral center as it does not have four different groups. A chiral molecule is a type of molecule that has a non-superposable mirror image. The feature that is most often the cause of chirality in molecules is the presence of an asymmetric carbon atom. The term "chiral" in general is used to describe the object that is non-superposable on its mirror image.

Stereoisomers are isomers that differ in spatial arrangement of atoms, rather than order of atomic connectivity. One of their most interesting type of isomer is the mirror-image stereoisomers, a non-superimposable set of two molecules that are mirror image of one another. The existance of these molecules are ...
WebA chiral centre is an atom that has four different groups bonded to it in such a manner that it has a nonsuperimposable mirror image. The term "chiral centre" has been replaced by the term chirality centre. In the molecule below, the carbon atom is a chirality centre. It has four different groups attached, and the two structures are ...
