The presence of a single chiral carbon atom sufficient to render the molecule chiral, and modern terminology refers to such groupings as chiral centers or stereo centers. An example is shown in the bromochlorofluoromethane molecule shown in part (a) of the figure below.

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. [16] [17] The term "chiral" in general is used to describe the object that is non-superposable on its mirror image. [18]

2023年1月23日 · Organic compounds, molecules created around a chain of carbon atom (more commonly known as carbon backbone), play an essential role in the chemistry of life. These molecules derive their importance from the energy they carry, mainly in a form of potential energy between atomic molecules.

In chemistry, a molecule or ion is called chiral (/ ˈkaɪrəl /) if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes.

This carbon, often designated by an asterisk in structural drawings, is called a chiral center or asymmetric carbon atom. If the bromine atom is replaced by another chlorine (Figure \(\PageIndex{2b}\)), the molecule and its mirror image can now be …

A molecule is said to be chiral if it lacks symmetry and its mirror images are not superimposable. To be chiral a molecule must lack symmetry, that is, a chiral molecule can not have any type or symmetry. Carbon atoms with four sp 3 hybridized orbitals can enter into up to four different bonds about the central carbon atom. When the central ...

The presence of a single chiral carbon atom sufficient to render the molecule chiral, and modern terminology refers to such groupings as chiral centers or stereo centers. An example is shown in the bromochlorofluoromethane molecule shown in part (a) of the figure below.

The carbon atom in a molecule of bromochlorofluoromethane is a chiral centre because it has 4 different substituents (H, Br, Cl and F). These two molecules, the "real" and "mirror image" bromochlorofluoromethane, are referred to as enantiomers.

The carbon atoms marked with a red asterisk are chiral carbon atoms. The middle carbon in the third molecule is only attached to three different groups. A simple example of chirality is your hands, the left and right are mirror images of each other, but cannot be superimposed.

The easy way to determine if a molecule is chiral is simply to look for the presence of one or more chiral centers: molecules with chiral centers will often be chiral. We can not say ‘always’ here because it is possible to come up with exceptions to this rule.
