Enantiomers have identical chemical and physical properties in achiral environments, while diastereomers have different properties in chiral and achiral surroundings. What can be deduced based on the observation that A smells like citrus fruits, while B has an odor of pine trees?
   
  1.A and B are diastereomers.
  2.A and B are an exception to the rule and do not have the same properties.
  3.The sense of smell cannot be used to deduce anything about the stereochemistry of A and B.
  4.The receptors responsible for smell are chiral.
  5.As can be observed by looking into a mirror, our noses are chiral.
