1. SELF.ORG.CHEM LECTURES THIS SAMPLE PRESENTATION IS 11 SLIDES LONG ABOUT 7 MIN READING EFFECTS AND SLIDES ADVANCE ARE AUTOMATIC BUT IN THE FULL LECTURE THESE ARE MANUALLY ACTIVATED FOR COMPLETE CONTROL BY LECTURER

2. SELF-ORG.CHEM WELCOME TO THIS SAMPLE OF: THE ART OF DRAWING ORGANIC COMPOUNDS A POWERPOINT PRESENTATION WITH ADVANCED GRAPHICS FOR MAXIMUM IMPACT ON STUDENTS

3. QUIZES WITH TIME LIMIT ON SCREEN SOLVED PROBLEM SHEET DETAILED SCRIPT TEXT FOR EACH SLIDE TO BE USED BY LECTURER IN CLASS SELF-ORG.CHEM INSTRUCTIONS FOR BEST RESULTS 24 INTERACTIVE SLIDES + 5 SLIDES ON ADVANCED RENDERINGS OF THE COCAINE MOLECULE SELF.ORG.CHEM LECTURES 2 MATERIALS INCLUDED IN THIS PACKAGE: 12345 Click mouse

4. 1 IN THIS LECTURE: Aliphatics: Explicit Hydrogens vs abbreviated line rendering: Drawing aliphatic compounds and branchingDrawing aromatics, planar structures Drawing alicyclics and the problem of non-planarity on paper A sophisticated example: the cocaine molecule Molecules and drawing types: from empirical to three dimensional SELF-ORG.CHEM 23456 3

5. OVERVIEW SELF-ORG.CHEM 4 There are several ways to depict molecules The art of drawing molecules in organic chemistry is like the art of writing. Molecular renderings become a language A clear language conveys clear ideas Iso-propanol is used as a first example of a few popular renderings on next slide

6. MOLECULAR RENDERINGS Stick or wire model Ball & stick model Space-filling model showing Van der Waals volumes SELF-ORG.CHEM = H = C = O = N = Cl = S Color codes of elements 5 SEVERAL STYLES DEPENDING ON WHAT YOU WANT TO EXPRESS

7. FROM THE EMPIRICAL FORMULA TO THE ABBREVIATED LINE RENDERING SELF-ORG.CHEM ISO-BUTANOL 6 EXAMPLE

8. Building our first molecule Iso-butanol C 4 H 10 O Empirical formula: atomic composition Condensed formula 1: minimum connectivity Expanded formula 2: better look at connectivity. Still time consuming to write down Line structures or abbreviated line rendering, most useful and used universally CH 3 CH 2 CH CH, CH 2, 2xCH 3, OH OH SELF-ORG.CHEM Group composition? 7

9. SELF-ORG.CHEM 8 FOUR SIMPLE STEPS TO GO FROM: TO: CH 3 CH 2 (OCH 2 CH(CH 3 ) 2 )CH(NH 2 )CH 2 CH 2 CHCHCH 2 CH(CH 3 )… … Clean simple, informative
