Certain organic molecules are chiral meaning that they are not superimposable on their mirror image. Chiral molecules contain one or more chiral centers, which are almost always tetrahedral (sp 3-hybridized) carbons with four different substituents. Consider the molecule A below: a tetrahedral carbon, with four different substituents denoted by ...

10 maj 2015 · Chirality can be determined by visualising the molecule in space. Once you do that, you can check to see if there exists a non-superimposable mirror image. If this is indeed the case, then your molecule is chiral.
A molecule or ion is chiral if it is non-superimposable, i.e. it can not be superimposed on its mirror image. This geometric property of a molecule is called chirality. Achiral is the reverse of chiral.
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.
23 sty 2023 · Chirality essentially means 'mirror-image, non-superimposable molecules', and to say that a molecule is chiral is to say that its mirror image (it must have one) is not the same as it self. Whether a molecule is chiral or achiral depends upon a certain set of overlapping conditions.
28 lut 2022 · A chiral molecule is a molecule that is not superimposable on its mirror image. eg. 1: Molecule 1 is not superimposable on its mirror image and, therefore, is chiral. eg. 2: Molecule 2 is not superimposable on its mirror image and, therefore, is chiral. An achiral molecule is a molecule that is superimposable on its mirror image. eg. 1:
