Under what conditions is a carbon atom chiral
WebCarbons in a ring can be chiral (if they bear different substituents) and the path traced around the ring from that carbon in one direction is different from that traced in the other Stereocenter (stereogeniccenter) an atom at which the interchange of two groups produces a stereoisomer Molecular Symmetry WebApr 3, 2024 · The four groups of atoms attached to the carbon atom can be arranged in space in two different ways that are like mirror images of each other. Note: The Bel-van't Hoff rule states that the number of stereoisomers of an organic compound is \[{2^n}\], where \[n\] is the number of chiral carbon atoms (unless there is an internal plane of symmetry).
