COURSE DESCRIPTION

This course gives introduction to organic chemistry and its importance. It reflects on qualitative and quantitative analyses of organic compounds. It reviews the principles of structure and bonding that will be useful as you learn about the chemistry of carbon compounds. This lecture uses the families of hydrocarbons known as alkanes, alkenes and alkynesto introduce the concepts of structure and nomenclature in organic chemistry. The course introduces other functional groups in organic chemistry.

COURSE OBJECTIVES

The skills you will learn in this lecture should enable you to:

Explain the various purification techniques used for organic compounds
Calculate the empirical formula and molecular formula of an organic compound from the data of the quantitative analysis
Describe the difference between ionic and covalent bonding
Understand the sp3,sp2, sp orbital hybridization bonding models
Explain homologous series
Identify functional groups in a given organic compounds
Explain the term isomerism, understand the difference between constitutional isomers and stereoisomers
Recognize the hydrocarbon families, functionally substituted derivatives of alkanes, alkenes, alkynes, aromatics, alcohols, aldehydes, ketones, monocarboxylic acids, amines, amides and classes of compounds containing the carbonyl group
Give the IUPAC names of the classes of organic compounds
Write structural formula for any organic compound, given the IUPAC name
Write a chemical equation for the preparation of a typical class of organic compound
State and write chemical equations for chemical rxns of alkanes, cycloalkanes, alkenes, alkynes, alcohols, aldehydes, ketones, amines, amides.
