On the following page, you will find the IR, 13C-NMR and ¹H-NMR for C6H12O. Determine the structure of the molecule. As you solve the structure, keep the following questions in mind: • What is the index of hydrogen deficiency for this formula? • Using the IR, what functional group(s) is (are) present in the molecule? What functional groups are missing? At what chemical shift range should look for corresponding peaks in the CNMR? In the HNMR? Are there peaks in those regions? • How many peaks are in the carbon NMR spectrum? How does it compare to the chemical formula? What might this tell you about the molecule? • How many peaks are in the proton NMR spectrum? How does it compare to the chemical formula? What might this tell you about the molecule? .

Which of the following is true about subatomic particles? Neutrons have no charge and are the lightest subatomic particle. Protons are a positively charged subatomic particle. Neutrons are a negatively charged particle located in the nucleus of an atom. The mass of a neutron nearly equals the mass of a proton. Electrons are negatively charged and are the heaviest subatomic particle. None of these are accurate Protons are positively charged and the lightest subatomic particle.
