Hello! I am in OCHEM 2 and im trying to figure out what my unknown is. Based off my many tests, the unknown has multiple bonds and a boiling point of 39-41 degrees celsius. Attached is the IR and NMR. I think my unknown is 1-pentyne. The unknown I have has a very pungent smell. The molecular formula is not given as the unknown is not given. A list of 35 possible unknowns are given.
