Quizplus · Accepted Answer

Statement 1 is false because a Fischer projection is a two-dimensional representation, not three-dimensional. Statement 2 is false because cyclic forms of aldoses result from intramolecular, not intermolecular, hemiacetal formation. Statement 3 is true; enantiomers have the same physical properties except for their optical activity and reactions in chiral environments.
