Based on the elemental analysis for your unknown organic compound, calculate its empirical formula. If your compound contains an unknown element (X), briefly explain how you identified which element it was. Make sure to show all calculations explicitly. 2. Determine the molecular formula of your unknown compound. Briefly explain how you arrived at your answer, referencing any relevant spectral data. 3. Based on your molecular formula, calculate the degrees of unsaturation present in your unknown organic compound. Make sure to show all calculations explicitly.

Identify and name all of the functional groups that are present in your unknown compound (i.e. alcohol, ester, alkyl halide, etc.). 2. Once you have identified your unknown, draw its structure directly on the IR spectrum and label all of the relevant peaks. Make sure to indicate whether each vibrational mode corresponds to a stretch or an out of plane bend. 13 arks Window Help 82% a blackboard.towson.edu onm Occidental Canbe Resort Empono Cancun, Ca Fights Lab 6-ldentifica H-NMR Spectrum: 1.
