  2. Chirality (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Chirality_(chemistry)

    Asymmetric molecules are always chiral. [6] The following table shows some examples of chiral and achiral molecules, with the Schoenflies notation of the point group of the molecule. In the achiral molecules, X and Y (with no subscript) represent achiral groups, whereas X R and X S or Y R and Y S represent enantiomers.

  3. Chirality - Wikipedia

    en.wikipedia.org/wiki/Chirality

    Conversely, a mirror image of an achiral object, such as a sphere, cannot be distinguished from the object. A chiral object and its mirror image are called enantiomorphs (Greek, "opposite forms") or, when referring to molecules, enantiomers. A non-chiral object is called achiral (sometimes also amphichiral) and can be superposed on its mirror ...

  4. Chiral drugs - Wikipedia

    en.wikipedia.org/wiki/Chiral_drugs

    Chemical compounds that come as mirror-image pairs are referred to by chemists as chiral or handed molecules. [1] Each twin is called an enantiomer. Drugs that exhibit handedness are referred to as chiral drugs. Chiral drugs that are equimolar (1:1) mixture of enantiomers are called racemic drugs

  5. Chiral media - Wikipedia

    en.wikipedia.org/wiki/Chiral_media

    For example, the molecules of cholesteric liquid crystals are randomly positioned but macroscopically they exhibit a helicoidal orientational order. Other examples of structurally chiral materials can be fabricated either as stacks of uniaxial laminas or using sculptured thin films .

  6. Inherent chirality - Wikipedia

    en.wikipedia.org/wiki/Inherent_chirality

    Spiro compounds (compounds with a twisted structure of two or more rings) can have inherent chirality at the spiroatom, due to the twisting of the achiral ring system. Inherently chiral alkenes have been synthesized through the use of a "buckle" where in an achiral, linear alkene is forced into a chiral conformation.

  7. Homochirality - Wikipedia

    en.wikipedia.org/wiki/Homochirality

    Some of these models propose three distinct steps: mirror-symmetry breaking creates a minute enantiomeric imbalance, chiral amplification builds on this imbalance, and chiral transmission is the transfer of chirality from one set of molecules to another.

  8. Planar chirality - Wikipedia

    en.wikipedia.org/wiki/Planar_chirality

    A planar chiral derivative of ferrocene, used for kinetic resolution of some racemic secondary alcohols [1]. This term is used in chemistry contexts, [2] e.g., for a chiral molecule lacking an asymmetric carbon atom, but possessing two non-coplanar rings that are each dissymmetric and which cannot easily rotate about the chemical bond connecting them: 2,2'-dimethylbiphenyl is perhaps the ...

  9. Optical rotation - Wikipedia

    en.wikipedia.org/wiki/Optical_rotation

    Compounds with these properties consist of chiral molecules and are said to have optical activity. If a chiral molecule is dextrorotary, its enantiomer (geometric mirror image) will be laevorotary, and vice versa. Enantiomers rotate plane-polarized light the same number of degrees, but in opposite directions.
