please answer all parts of the question with detail

4. (12 points) In a laboratory experiment, the reduction of butanone has left you with the racemic mixture of 2butanol, which you want to resolve using just one reagent. a) Circle the appropriate reagent for the racemic resolution and indicated briefly (in 2 or 3 words each) why you reject each of the others. b) Draw the diastereomers that result from the reaction and give the configuration of all stereocentres. c) Give a short description of how you would continue with the diastereomeric mixture to get the enantiomerically pure alcohols. 4.
