Document Summary

This molecule is an enantiomer since it is not superimposable. It has an (r) configuration, as the first-priority group, through the second, and then to the third, has a clockwise rotation. This molecule is also an enantiomer because it cannot be superimposed. From the original image (right), the priority groups sequence is rotating in a clockwise direction. However, the hydrogen is located at the front. So by rotating it to the back, the sequence will have a counter-clockwise rotation. Thus, the original image has an (s) configuration: ch3ch(oh)ch(cl)ch3. Since this compound is not superimposable, it is an enantiomer. There are two chirality centers found in this molecule, and both of them each have (r) configuration. For the mirror image, both centers have (s) configuration, and the rotation of the priority group is counter-clockwise. This molecule is considered as an enantiomer because it cannot be superimposed.
