C Problem Br H What are Ha and Hb A Enantiomers Hb B Enantiotopic protons C Homotopic protons D Diastereotopic protons E Chemically equivalent D Solution and explanation The answer here would be D diastereotopic protons In order to figure out the relationship between protons a and b you can take the shortcut mentioned above Since there is a chiral center in the molecule the protons bonded to the carbon would not be chemically equivalent As mentioned earlier if the protons are not homotopic or enantiotopic they are not chemically equivalent The opposite of this is true well If they are not chemically equivalent they are neither homotopic or enantiotopic This eliminates choices b c and e Ha and Hb would not be enantiomers because enantiomer term used for isomers not protons If Ha and Hb produced enantiomers during the replace test they would be considered enantiotopic protons Therefore the only option left is d diastereotopic protons
