Final answer:
Enantiomers are mirror images of each other and have the same chemical structure but differ in the arrangement of atoms in three-dimensional space. The molecule shown does not have enantiomers because it lacks the necessary four different atoms or groups connected to a central carbon.
Step-by-step explanation:
Enantiomers are molecules that share the same chemical structure and chemical bonds but differ in the three-dimensional placement of atoms so that they are non-superimposable mirror images. In order for a molecule to be an enantiomer, it must have at least four different atoms or groups connected to a central carbon. In the case of the molecule shown below, it appears to have only two different groups, so it does not have enantiomers.
