(f) Which of the following is true about an enantiomer of Lunesta? Identify all that apply: (1) The enantiomer rotates plane-polarized light in the opposite direction as Lunesta. (2) The enantiomer is a mirror image of Lunesta. (3) The enantiomer has the opposite biological effects as Lunesta (i.e., it keeps you awake). (4) Lunesta does not have an enantiomer.
