• Plzz plzz help. How can we draw the diastereomers of 2,3-dibromobutane.??? Is it follow the #2^n rule for stereoisomers????
  
• Suppoose "A" Is any molecule whose mirror image is "B". The " A" Nd "B" Are not superimposed.The mirror image of "B" is "C". The " C" Is superimposed to "A". So what can we say molecule "A" Is chiral r Achiral.????plzzzz help.
