Concept explainers
(a)
Interpretation: The given compound is to be labeled as chiral or achiral.
Concept introduction: A carbon atom that has four nonequivalent atoms or groups attached to it is known as chiral carbon atom. Chiral carbon centers are also called as asymmetric or stereogenic centers.
Achiral compounds have plane, axis or center of symmetry and are superimposable on its mirror image.
