What is a chiral and achiral?

In chemistry, chirality usually refers to molecules. Two mirror images of a chiral molecule are called enantiomers or optical isomers. Enantiomers pairs are often called “right”, “left handed” or if they have no achiral damage.

An extensive study and analysis of chirality, classification, presentation and nomenclature of chirality and lack of chirality in crystalline structures and their constituents is presented. The oriented crystalline structures are classified.

Examines chirality rules for the existence of molecular crystal structures and highlights the relationship with latent segmentation and symmetry. The nomenclature of chirality and related terms, as well as the chirality relationship with optical activity, are covered. The uses and limitations of the Euclidean normator are treated. An improved glossary of terms is included.
