Elementary Organic Chemistry 211 Prof. Rau ! Posted on 20th November 2016 by Steve Smith. Qualitative organic analysis, the identification of organic compounds based on their physical and chemical properties, is analogous in some ways to the identification of plants and animals according to their taxonomy--their structural features and presumed natural relationships. In identifying complex molecules, one must take account of the mutual effect of functional groups … endobj Fehling’s Test: Take 1 ml each of Fehling’s solution A and B in a test tube. Title: Detection and confirmation test for functional group. To develop skill in the recognition of characteristic absorption bands; 4. 2 0 obj R-OH bond has an IR absorption that is between 3500-3600 cm-1 (Padias 72). At the top of the report write your name, the experiment number and title, your lab section, and the names of any group members (if it was a group experiment). The synthesis of low molecular weight esters, by the reaction of a carbonyl with an alcohol, is essential to the fragrance and flavoring industry. Write a full lab report (description of experiment, methods, data, analysis, discussion, ... functional group chemistry 3. We did a lab for functional group analysis and I missed the lab but stil need to complete the report. Functional groups are structural units within organic compounds defined by specific atom and bond arrangements. Chemists frequently use qualitative patterns of reactivity to identify the functional groups of unknown compounds. The qualitative tests performed in this experiment were to analyze the compounds for any functional groups… functional groups. Background Required: You should be familiar with techniques for weighing, measuring by volume, and mixing in a test tube, as well as analysis of 1H NMR and 13C NMR spectra. 4 0 obj Figure 2. Ketones/aldehydesa carbon-oxygen double bond, where the carbon is also attached to two. other carbons (ketones) or to a carbon and hydrogen (aldehyde). This experiment will introduce you to some of the more common functional groups of organic chemistry. dropsofa!2%aqueouspotassiumpermanganate!solution.!! important, the pre-lab write-up for this lab is worth 10 points (and the write-up is worth 10). CHEM 211 students may run IR spectra only during their regularly scheduled laboratory time. carbons can In functional group analysis of organic compounds, it is assumed that an organic molecule can be considered as a sum of virtually independent functional groups, whose properties determine the physical and chemical properties of the compound. iY����d!��o���E��� ��������}&1�KN��7�[���ɛ�����D����ɹtY䥮��\g�s~�n�?�ۉ�j��.�ﶓs ������:�a�S�]�����f ����|�����P�g)Rƺ����=����iU��H�r$M��3��BCK��Zp�KQ�O�EH��F��sq�����~��c Compositional analysis, functional group correlations, and back trajectories were used to identify three types of events with source signatures: primary biogenic-influenced, urban-influenced, and regional … Determine organic products formed via substitution, elimination, addition and rearrangement reaction and the associated mechanisms 4. This semester, all of your unknowns are listed in the Manual but you can consult other texts such as Shriner, Fuson, Curtin, "The Systematic Identification of Organic Compounds", Vogel, "Elementary Practical Organic Chemistry, Part 2, Qualitative Organic Analysis", "CRC Handbook of Tables for Organic Compound Identification"--all of these are in the lab and available to you. 10: Organic Functional Group Analysis Pre-Lab Assignment Section # Score This lab provides a review of the physical and chemical properties of six of the most important organic functional groups. This exercise in qualitative analysis will allow you to apply the principles and techniques that you have learned throughout this year in organic chemistry lab. tests, selective functional group tests and spectral analysis. If you have not already done so, you should read my previous post and ensure that you are familiar with the chemical tests listed here.
