WebApr 14, 2024 · Chiral molecules are non-superimposable mirror images of each other and exist as enantiomers. The term "chirality" comes from the Greek word "kheir," which means hand, as many chiral objects have handedness, like our hands. Enantiomers: Enantiomers are pairs of stereoisomers that are non-superimposable mirror images of each other. WebStructurally, Cu18H may be also viewed as sandwich type of sulfur-bridged chiral copper cluster units [Cu6-Cu6-Cu6], endowing three-layered 3D chirality.

Web2. Stereoisomers having chiral centers - Most stereoisomers discussed in this chapter will fall into this category. Chiral centers are tetrahedral atoms (sp 3 hybridized) that are bonded to 4 different groups. In organic chemistry most chiral centers will be carbon atoms, but chiral centers could technically be any tetrahedral atom.
