QUESTION: determine the structures of Compounds A, B, C, D, and E. Show calculations. Support all of your structure determinations. Student performed a sodium borohydride reduction experiment. He followed a standard procedure for performing such reduction reactions and workup and isolation protocols. Student's starting material was Compound A. In his reduction reaction with Compound A, he obtained four products, Compounds B, C, D, and E. In an elemental analysis experiment, Compound A was shown to be 81.05% carbon and 4.55% hydrogen. In separate elemental analyses experiments, Compounds B, C, D, and E were shown to be 79.60% carbon and 6.25% hydrogen.
