You have an unknown molecule, Molecule Q, which has a molecular formula of C_10H_18. When you react this molecule with H2 over a platinum catalyst the resulting molecule has the molecular formula of C_10H_20. When you react this molecule with warm KMnO_4 followed by an acidic water treatment you determined that one of your products is a 4-carbon ketone (2-butanone) and an unknown molecule, Molecule R which is also a ketone. What are the structures of molecules Q and R?...
