C Postlab-Each student must write his or her report individually - no joint reports with lab partners! The postlab report must be typed, although chemical reactions and structures may be handwritten. The postlab report should consist of a table (see example on the following page) in which all the information about each chemical test (the name, procedure, observations, reaction and conclusion) is tabulated horizontally. Chemical tests should be listed in a logical order, preferably in the order in which they were performed. Note that procedures must be written in a passive, past tense and that chemical reactions must be depicted for your specific unknown. NMR Analysis - An NMR analysis section must be appended in your postlab report for the unknown compound. In the NMR analysis section, you must do your best to identify every peak in the NMR spectrum and indicate what proton(s) they correspond to. For every peak, you must discuss how its three properties (integration, chemical shift and splitting) agree or do not agree with your proton assignment and your decision about the identity of your unknown (see sample format below). You must submit a hard copy of your NMR spectrum with your lab report. Sample NMR Format (for a molecule with four types of H in it) Integration Shift Splitting На нь Hc Ha
