6. Provide at least one fragment (not the parent ion) that was useful in determining (or confirming) the structure of the unknown and briefly explain how it was useful. 7. Give several pieces of data you gathered from the IR spectrum that aided in determining (or confirming) the structure of your unknown. For example, you might mention the presence (or absence) of certain definitive peaks (include wavenumbers). Do NOT use anything from the fingerprint region.
