Chiral centers vs stereocenters

WebApr 28, 2024 · Any atom in an organic molecule that is bonded to four different types of atoms or chains of atoms can be considered "chiral". If a carbon atom (or other type of atom) has four different substituents, that carbon atom forms a chiral center (also known as a stereocenter). Chiral molecules often have one or more stereocenters. WebAnswer (1 of 6): The two terms are often used interchangeably. For example, quoting from Clayden et al.: > If a molecule contains one carbon atom carrying four different groups it will not have a plane of symmetry and must therefore be chiral. A carbon atom carrying four different groups is a s...

This important type of stereoisomer occurs because carbon sp 3 tetrahedral centers can allow a molecule to show chirality. Chirality exists when the mirror image reflection of a configuration at an sp 3-hybridized center cannot be exactly superimposed, or placed to match exactly, on the original.

WebDec 17, 2024 · A meso compound contains a plane of symmetry and so is achiral, regardless of whether the molecule has a chiral center. A plane of symmetry is a plane that cuts a molecule in half, yielding two halves that are mirror reflections of each other.

WebCis and trans double bonds are sterogenic centers in that two different compounds are possible that are stereoisomers (diasteromers). However, that is not sufficient.
