LECTURE 1 SYLLABUS FOR FIRST CLASS 2013-2014 MSC. ISMAIL M.ALI DEPARTMENT OF CHEMICAL ENGINEEING COLLEGE OF ENGINEERING TIKRIT UNIVERSITY MANDATORY CLASS: 1ST ORGANIC CHEMISTRY Teaching scheme: 2 hours lecture per week CH 122 Credits: 6 Course description Is an introduction to organic chemistry, focusing primarily on the basic principles to understand the structure and reactivity of organic molecules. Emphasis is on substitution and elimination reactions and chemistry of the carbonyl group. The course also provides an introduction to the chemistry of aromatic compounds. Objective • To impart the basic concepts of organic chemistry • To develop understanding about concepts on organic reactions for analysis of unit processes Specific learning outcome The mechanisms can be described in terms of electron shifts, Radical substitution vice versa of alkanes. The physical properties will be explained in terms of the intermolecular forces.

ORGANIC CHEMISTRY Chemistry of compounds that contain carbon Combine mainly with hydrogen, oxygen, and nitrogen Over 10 million compounds made with these 4 elements 95% of compounds contain carbon Form stable, covalent bonds with each other PROPERTIES Organic (Benzene) Low melting pts Low boiling pts Low solubility in water Highly flammable Nonconductive Covalent bonds Inorganic (NaCl) High melting pts High boiling pts Soluble in water Nonflammable Conductive Ionic bonds HYDROCARBONS Compounds containing only two elements Carbon and hydrogen Alkanes: Structures and Names Objectives Identify an alkane Determine what an isomer of an alkane is Identify different types of alkanes ALKANES Saturated Hydrocarbons Called saturated because each carbon is bonded to four other atoms Only single bonds Methane Ethane Propane HOMOLOGY Related compounds Homologs Have properties that vary in a regular and predictable manner A manner of organization Similar to P.T. ISOMERS Different compounds having the same molecular formula Butane Isobutane (isolated branched chain) Pentane Isopentane Neopentane ISOMERS ALKANES CnH2n+2 Representation Structural Formulas Condensed Structural Formulas Butane ALKYL GROUP A group of atoms that results when one hydrogen atom is removed from an alkane CnH2n+1 Change –ane ending to –yl Methyl Ethyl Propyl IUPAC NOMENCLATURE Define IUPAC Examine the rules for IUPAC naming Determine the correct names of alkanes Geneva, Switzerland 1892 International Union of Pure and Applied Chemistry IUPAC System of Nomenclature (isobutane, isopentane are common names) IUPAC RULES 1. Name the longest chain in the parent compound. End in –ane. (Root name) Number each carbon See Example 2. Note the alkyl groups attached 3. Number the carbon that the group is attached to. Must use the lowest number possible. See Example IUPAC RULES CON’T 4. Use prefixes to indicate the amount of attached groups See Example 5. If there are more than two or more different substituents, list them in alphabetical order. If at equal points, lower alphabetical order given lowest number See Example 6.
