Analyzing and Predicting Spectroscopic Data

The interaction of electromagnetic radiation with the structure of molecules in the sample and their study is referred spectroscopy. Several spectroscopic methods are used to acquire sample information, and these methods are proved to be accurate, fast, and non-destructive. The information obtained about the content and composition of molecules from these spectroscopic methods is called spectroscopic data.

Please identify compound 1 and compound 2!!! Attached is the H-NMR and IR for both compounds (ignore the IR peaks ~2400). The experimental melting point for the aqueous layer was 260-261 celcius. The experimental melting point for the organic layer was 76.9-78.7 celcius. The following was my procedure: IntroductionThe reaction mixture in this experiment contains 4-bromobenzaldehyde, methanol, and aqueous potassium hydroxide. A reaction occurs that produces two organic compounds, compound 1 and compound 2. Both are solids at room temperature. Your task is to isolate, purify, and identify both compounds. A specific procedure is given for preparing the compounds, but you will need to work out the procedures for most other parts of this experiment.Experimental ProcedureThis procedure should produce enough of each compound to complete the experiment; however, in some cases, it may be necessary to run the reaction a second time.
