The concept defines a chiral center (or stereocenter) in organic chemistry as a saturated carbon atom bonded to four distinct substituent groups, which is the necessary condition for optical activity and molecular non-superimposability on its mirror image. Primary carbons with three identical hydrogens or secondary carbons lacking additional substituents are formally excluded from this classification due to symmetry. This principle dictates that the number of possible stereoisomers in a molecule containing *n* chiral centers is theoretically calculated as 2^n, forming the basis for predicting stereochemical complexity without enumerating specific structural instances.
