For the following problem, use a separate sheet of paper for your answer and then upload your answers at the following link: https://canvas.dccc.edu/courses/28473/assignments/574397 Your work must be shown for full credit.     A C6H12hydrocarbon (A) reacts with 1 molar equivalent of H2 over a palladium catalyst. Hydrocarbon (A) also reacts with OsO4 in pyridine to give diol (B). When oxidized with KMnO4 in acidic solution, (A) gives two fragments – a carboxylic acid (C) and another fragment (D). Draw the structures for A, B, C, and D and show how you arrived at your answers using chemical equations.
