above molecule.
b. It would be theoretically possible to design a molecule that would be a structural isomer of the
above molecule.
c. It would be theoretically possible to design a molecule that would be an enantiomer of the
above molecule.
d. None of these statements are true. - CORRECT ANSWER: C
