Stereoisomers . are compounds that have the same structural formula in terms of order of attachment, but differ in arrangements of the atoms in space.. The difference in odor between caraway seeds and mint leaves arises from two stereoisomers of carvone due to different arrangement of atoms at the carbon (*). Two molecules are isomers of each other if they have the same molecular formula, but they are different in some way.. Their atoms can be connected in different ways; they can differ as a result of rotations about single bonds; or they can be mirror images of each other.. Chapter 22.

Two or more different compounds having the same molecular formula are called isomers and the phenomenon is called isomerism. Isomerism arises due to specific spatial dispositions of the atoms in a molecule. Due to covalence of M-L bonds, many types of isomers occur in co-ordination compounds. However, compared to organic compounds, relatively few inorganic compounds exhibit isomerism. .
